Evaluates the given expression, then puts the result of that on the timequeue, to execute after the given number of seconds. At that time, the string is evaluated again, and displayed to the user, or to the room, depending on whether it was run from a regular message such as @succ, or from an omessage such as @osucc. Since the expression is evaluated both before and after being delayed, you need to put MPI code that is to run after the delay within a {lit:expr} command. If a {delay} evaluation is a null string, then the notify or notify_except will not be done. {delay} will return the process ID of the event it puts on the timequeue.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{kill:processID}
Kills a process on the timequeue, that was possibly created by {DELAY}. If the process ID it is given is 0, then it will kill all processes done by that trigger object. If the process to be killed was not set off by that trigger, and was not set off by any object that the owner of the trigger owns, then this will error out with Permission denied. If no process is found, this returns 0. If a process was found, and the permissions were okay, then the process is killed, and {kill} returns the number of processes killed. Usually one.

{if:check,true,false}
This is a simple conditional command. It evaluates the 'check' argument and if it is true, then it evaluates the 'true' argument and returns it's result. If 'check' does not evaluate as true, then it will evaluate the 'false' argument, if there is one, and returns it's result. If there is no false argument, and 'check' evaluated false, then it returns a null string. Example: Your computer is {if:{eq:2,3},broken!,All right.}

Returns true if expr1 or expr2 evaluate as true. Otherwise, this returns false. If expr1 was true, this doesn't bother to exaluate expr2, as it does C-style shortcutting. If there are more than two arguments, then this will evaluate them until either one returns true, or until it has evaluated all the expressions. This returns false only if all of the expressions return false.

{prop:propname,obj}
Returns the literal string value of the given property. If no object parameter is passed to it, it looks for the property somewhere down the environment from the trigger object. Otherwise, it looks down the environment from the object specified. If the property is not found, this returns an empty string. If the property that it tries to access is read restricted and the owner of the trigger object does not own the object that the property is found on, then the MPI script stops with a Permission denied error.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{prop!:propname,obj}
Returns the literal string value of the given property. If no object parameter is passed to it, it looks for the property on the trigger. Otherwise, it looks for the property on the object specified.

{index:propname,obj}
Returns the string value of the property whose name is stored in the given property. This sounds confusing, but it's basically just the same as {prop:{prop:propname}}. If no object parameter is passed to it, it looks for both the index property and the referenced property somewhere down the environment from the trigger object. Otherwise, it looks down the environment from the object specified for both of them. If either property is not found, this returns an empty string. If the property that it tries to access is read restricted, and the owner of the trigger object does not own the object that the properties are found on, then the MPI script stops with a Permission denied error.

{store:val,prop,obj}
Stores a string value in a given property. If no obj parameter is given, then it stores the property on the trigger object. Otherwise, it will store it on the given object. If you specify a propname that is protected, you will get a Permission Denied error. You are only allowed to store properties on objects controlled by the owner of the trigger object. The trigger object is the object that triggered the evaluation of the MPI commands. This function returns the string that is stored as the prop value. If you store a null value in the property, then it will remove the property if it is not a propdir. It will clear the value of the prop if it IS a propdir.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{delprop:propname,object}
This function will remove a property and all of it's subsidiary properties in the case that it is a propdir. This will delete the property on the trigger object, unless an object argument is specified. If one is, then it will delete the property on that given object. This function returns a null string. If you specify a propname that is protected, you will get an error of Permission Denied. You are only allowed to delete properties from objects that are owned by the owner of the trigger object.

{list:listname,obj}
Returns a string, containing a carriage-return delimited list of individual lines from a property based list. A property based list is a series of properties that are consecutively numbered. The server understands several different formats, and can also read in property lists in either the propnameX format, or the propname#/X format. It does NOT evaluate the contents of the list for embedded MPI commands. If no obj argument is supplied, then it looks for the list somewhere down the environment from the trigger object. Otherwise, it looks for the list down the environment from the given object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{concat:listname,obj}
Returns a string, containing the concatenated lines of a property based list. It concatenates the list semi-intelligently, putting a single space between lines normally, and two spaces between lines when the previous one ended with a period, exclamation mark, or question mark. A property based list is a series of properties that are consecutively numbered. The server understands several different formats, and can also read in property lists in either the propnameX format, or the propname#/X format. It does NOT evaluate the contents of the list for embedded MPI commands. If no obj argument is supplied, then it looks for the list somewhere down the environment from the trigger object. Otherwise, it looks for the list down the environment from the given object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{lexec:listname,obj}
This takes a property based list, and concatenates all its lines together, stripping spaces from the beginning and end of each one. It then evaluates the result for MPI commands, and returns the resulting string. A property based list is a series of properties that are consecutively numbered. The server understands several different formats, and can also read in property lists in either the propnameX format, or the propname#/X format. If no obj argument is supplied, then it looks for the list somewhere down the environment from the trigger object. Otherwise, it looks for the list down the environment from the given object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{rand:listname,obj}
Returns the value of a randomly picked list item from a property based list. If no obj parameter is given, then it looks down the environment from the trigger object for the list. Otherwise, it looks down the environment from the given object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{select:value,listname,object}
Returns the value of a single list item from a sparse property list. The item chosen is the one who's line number is the largest one that is less than or equal to the given value. If the list is missing any items, then {select} will return the item in the list with the highest line number that is less than or equal to the given value. ie: If the list has the following entries:
_junk#/1:one
_junk#/5:two
_junk#/16:three
_junk#/20:four
Then {select:9,_junk} will return "two", {select:16,_junk} will return
"three", and {select:25,_junk} will return "four".

{timesub:period,offset,listname,object}
This is sort of like {list}, except that it will only return one line of the given named property list. The line it chooses depends on the time. The period is the length of time, in seconds, that it takes for {timesub} to cycle through the entire list. The offset is the number of seconds to offset into the time period, if you actually need to synchronize the {timesub} with something. The offset usually is just left at zero. If the object argument is not passed, it looks for the list on the trigger. What this all means, is that if you have, for example, a period of 3600 (one hour), an offset of zero, and a property list that has six items in it, then {timesub} will return the first line of the property list during the first ten minutes of the hour, the second line during the next ten minutes, and so on, until it returns the last line during the last ten minutes of the hour. Then it returns the first line for the beginning of the next hour. Here's an example:
{timesub:86400,0,_sunmoon}
This example will show different property list lines, depending on the
time of day. The period is 86400 seconds, which is one day. If the
property list has 24 items in it, then a different line will be returned
for each hour of the day.

* matches any number of any character.
? matches one character, of any type.
[abcde] matches one char, if it is a, b, c, d, or e.
[a-z] matches one char, if it is between a and z, inclusive.
[^abd-z] matches one char is it is NOT a, b, or between d and z.
{word1|word2} matches one word, if it is word1, or word2.
{^word1|word2} matches one word, if it is NOT word1 or word2.

{midstr:str,pos1,pos2}
Returns the substring that starts at pos1 within str. If no pos2 is given, then the returned string is only the character at the given pos1 position. if a pos2 position is given, then it returns the substring beginning at pos1 and ending at pos2, inclusive. If pos1 or pos2 are negative, then they represent the position that is that absolute number of characters from the end of the string. The first character in str is 1, and the last one can always be referenced by -1. If a position would be before the beginning of the string, it is assumed to be at the beginning of the string. If it would be beyond the end of the string, it is assumed to be at the last character. If the starting position is later in the string than the ending position, then the returned string has the characters in reverse order. If either pos1 or pos2 are 0, then this returns a null string.

{tell:string,player}
If passed only a string, tells the user that string. If passed both a string, and a player dbref, it will tell the given player the message. This returns the message that was sent. If the trigger isn't a room, or an exit on a room, and if the message doesn't already begin with the user's name, then the user's name will be prepended to the message. The two exceptions to this are that if the messages is being sent to the owner of the trigger, or to the user, then the user's name will not be prepended.

{otell:string,room}
{otell:string,room,player}
This will tell the given string to all the players in the room, except for the given player. If no room argument is given, it is assumed to be the room that the triggering player is in. If no player is given, then it assumes that you want to skip sending the message to the triggering player. If you pass it a player of #-1, it will send the message to all the players in the room. This returns the message that was sent. If the trigger isn't a room, or an exit on a room, and if the message doesn't already begin with the user's name, then the user's name will be prepended to the message.

Acts as a counting loop, like BASIC's for loops. The varname is the name of the variable that it will create and use to store the count value. The start value will be the initial value of the variable, and the end value will be the value that the variable is working towards. The increment is how much the variable will be incremented by in each loop. The command will be eval- uated for each value of the variable between the beginning and ending values. For example: {null:{for:i,10,1,-1,{tell:{&i}}}} will echo a countdown from ten to one, inclusive, to the user.

{foreach:var,list,expr,sep}
This evaluates expr for each and every item in the given list. On each evaluation, the temporary variable var will contain the value of the item under scrutiny. var will only be defined for the duration of expr, and will be undefined after the {foreach} construct finishes. If sep is given, then it uses that string as the item seperator in list, instead of the usual carriage return character. sep can be multiple characters long. This structure returns the result of the last evaluation of expr. Example: {foreach:thing,{contents:here},{store:1,_seen}}

This evaluates expr for each and every item in the given list. On each evaluation, the temporary variable var will contain the value of the item under scrutiny. This function returns a list containing all of the items from the input list, for which expr evaluated true. var will only be defined for the duration of expr, and will be undefined after the {filter} construct finishes. If sep is given, then it uses that string as the item seperator in the input list, instead of the usual carriage return character. If s2 is defined, then it will use that string to seperate the items in the list it returns, instead of the normal carriage return. sep and s2 can be multiple characters long.

{parse:var,list,expr,sep}
{parse:var,list,expr,sep,s2}
This evaluates expr for each and every item in the given list. On each evaluation, the temporary variable var will contain the value of the item under scrutiny. This function returns a list containing the output of expr for each item within the list. This lets you do direct translat- ion of a list of dbrefs, for example, into a list of names. var will only be defined for the duration of expr, and will be undefined after the {filter} construct finishes. If sep is given, then it uses that string as the item seperator in the input list, instead of the usual carriage return character. If s2 is defined, then it will use that string to seperate the items in the list it returns, instead of the normal carriage return. sep and s2 can be multiple characters long.

{fold:var1,var2,lst,expr,sep}
This takes a list and stores the first two items in var1 and var2, then evaluates expr. The value returned by expr is then put in var1, and the next list item is put in var2. Expr keeps being evaluated in this way until there are no more list items left. This returns the last value returned by expr. If a sep argument is given, the input list is assumed to have its individual items delimited by that string, otherwise it assumes a carriage return.

Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the name of the given object. If the object is an exit, the name returned is the first exit name it has before the first ';'. The object must be in the vicinity, or controlled by the owner of the trigger object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the name of the given object. In the case where the object is an exit, then the full name of the exit is given, including all the ; aliases. The object must be in the immediate vicinity, or be controlled by the owner of the trigger object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the owner of the given object. The object must be in the vicinity, or be controlled by the trigger object's owner.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the location of the given object. The object must either be in the vicinity, or it must be controlled by the owner of the trigger object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns a flaglist string from obj. ie: PM2J. The object must either be in the vicinity, or it must be controlled by the owner of the trigger object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{controls:obj,player}
If one argument is given, then this returns true ("1") if the trigger object's owner controls the given object. If two arguments are given, then it returns true if the given player controls the given object. Otherwise, this returns false. ("0") Wizards control everything.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{nearby:obj,obj2}
If one argument is given, then this returns true ("1") if the given object is nearby to the trigger object. If two arguments are given, then it returns true if the two objects are nearby one another. Otherwise, this returns false. ("0") Nearby is defined as: 1) The two objects are in the same location, or 2) One object contains the other, or 3) the two objects are in fact the same object.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
This returns the value of an object of TYPE_THING, or returns how many pennies a player has.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the type of an object. The possible values are: Bad, Room, Exit, Thing, Player, and Program.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns true if the given object if of the given type. Valid types are: Bad, Room, Exit, Thing, Player, and Program.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{contents:obj,type}
Returns a list of the contents of the given object. If a second argument is passed to it, it restricts the listing to only those objects that are of the given type. Either the object must be nearby the trigger object, or else the owner of the trigger object must control the object. Otherwise this will error out with a Permission Denied error. The valid object type values are Room, Thing, Exit, Player, Program, and Bad. HINT: If you need to get a list of two types of objects from the room, just concatenate the lists from two calls to this function, with each object type you want. ie:
{mklist:{contents:here,player},{contents:here,thing}}
or
{contents:here,player}{nl}{contents:here,thing}
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns a list of all the exits on the given object. The owner of the trigger object has to control obj, or else this errors out with Permission Denied. Programs and exits never have exits attached to them.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the object reference of what the given object if linked to. Since exits can be meta-links, linked to multiple exits, if there is more than one link, then this function returns a list of all the destinations, seperated by carriage return characters. (\r)
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Forces the given player or thing to do the given command. The thing forced must be @flock'ed to the trigger object, or the trigger object's owner, and it must be set XFORCIBLE, or else this function will get a Permission Denied error. This function returns a null string. {Force} cannot force a thing-object to do something, if it is set Dark, is in a room set Zombie, or is owned by a player set Zombie.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns true if obj1 and obj2 refer to the same object. This does name matching, so {dbeq:*Wizard,#1} will return true if #1 is named Wizard.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Tests the _/lok (@lock) standard lock property on obj against the given player. Returns true if the lock is locked against the player.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{testlock:obj,prop,who}
{testlock:obj,prop,who,def}
Tests the lock property 'prop', on 'obj' against the given player 'who'. If no 'who' argument is given, then it checks the lock against the using player. If a def argument is given, then the lock will default to that value, if there is no lock property of the given name on the given object. Returns true if the lock is locked against the player.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{holds:obj1,obj2}
Returns true if the location of obj1 is obj2. If no obj2 argument is given, then this will return true if the location of obj1 is the player.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{contains:obj1,obj2}
Returns true if obj1 is within obj2, or within anything it contains, or within anything they contain. If obj2 is not given, then it checks to see is obj1 is held by the player, or by anything they hold, etc. Basically, this just sees if obj1 is within the locational environment of obj2.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns a list of players who are online. This function can only be executed by wizbitted objects.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns how many times player is connected. This means that it will returns 0 if the player is not connected. If the given object is NOT a player, it will return 0. In all other cases, it will return a positive number, being how many times the given player is connected to the server.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns player online time in seconds. If the given player is not connected, or is not a player object at all, then this will return -1. This returns the online time for the most recently connected connection, if there are multiple connects.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns player idle time in seconds. If the given player is not connected, or is not a player object at all, then this will return -1. This returns the idle time for the most recently connected connection, if there are multiple connects.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{&var}
These are two ways of trying to do the same thing. They return the value of the named variable var. If there is no variable with the given name currently defined, then this gives an error stating as much. Variables can be defined either with the {with:} function or within a looping command.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
This sets the value of the given named variable to the given value. If no variable with that given name is currently defined, then this gives an error message complaining about that.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
This defines a new variable with the given name, and sets it's value to the given val. Up to 7 expr's are allowed, but the only value returned to {with}'s caller, is the value returned by the evaluation of the last expr. If there is already a variable of the same name, then this command will override that variable, for the duration of the {with:} command. The new variable is only valid to use within the confines of the {with:} command, and it will go away after the command completes. This provides scoped variables quite effectively. NOTE: There can be no more than 32 variables defined at any one time, total. This includes variables that are defined within macros, or properties or lists that are executed with {exec:} or {lexec:}. Here's an example to illustrate the scope of variables inside of {with:} commands:
{prop:_mydesc} <- {&people} not defined.
{with:people,{contents:here,players}, <- Defining. Not available yet.
{if:{count:{&people}}, <- It's usable now.
The players awake here are
{lit: } <- just puts in a space.
{commas:{&people},{lit: and },
who,{name:{&who}} <- uses {&who} as temp var.
} <- {&who} no longer defined.
}
} <- {&people} no longer defined.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{count:list,sep}
This counts the number of \r delimited items that are in the given list. This is effectively a list item count. If the sep argument if given, then it counts the number of sep delimited substrings in list. ie: The default sep is \r. (A carriage return.)
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
This returns a list with all the given values as list items, seperated by carriage returns. ('\r's) Example: {mklist:Tom,Dick,Harry} returns "Tom\rDick\rHarry". Note: A maximum of nine items can be passed to the {mklist} function. If you need more, you can chain {mklist}s together. Example: {mklist:{mklist:a,b,c,d,e,f,g,h,i},j,k,l,m,n,o,p}
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{sublist:list,pos1,pos2}
{sublist:list,pos1,pos2,sep}
Takes a list, and returns a subset of the list items within it. The subset is all the list items between list item pos1, and list item pos2, inclusive. If the pos2 argument is omitted, it assumes that pos2 is the same as pos1. If pos2 is less than pos1, then all the list items between pos2 and pos1 are returned, in reversed order. If pos1 or pos2 are negative, it counts that many list items back from the end of the list, so -1 is the last list item, and -5 would be the fifth from last list item. The input list is assumed to be delimited by carriage returns (\r) unless the sep argument is given.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{lrand:list,seperator}
Returns a randomly picked stringlist item from the given list. If the seperator argument is given, then it will assume that the stringlist has it's items delimited by the given seperator string, instead of by carriage returns.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns list with all duplicate items removed.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Combines the contents of list1 and list2, removing any duplicates.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Creates a list containing every item that appears in BOTH list1 and list2. Any duplicate items in the resulting list are removed.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the contents of list1, with any items that match an item in list2 removed. The resulting list has all duplicate items removed.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{lmember:list,item,delimiter}
Returns true, if the given item is in the given list. If the delimiter argument is given, then it treats the list as if it were delimited by that string, instead of by carriage returns. (\r's)
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{lsort:list,var1,var2,expr}
Returns the sorted contents of list. If 4 arguments are given, then it evaluates expr with a pair of values, in var1 and var2. If expr returns true, then it will swap the positions of the two values in the list. It runs this comparison on every pair of items in the list, so it will be evaluated N*N times, where N is the number of items in the list. This method can also be used to randomize a list. Example: {lsort:{&list},v1,v2,{gt:{dice:100},50}}
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
{commas:list,lastsep}
{commas:list,lastsep,var,expr}
Takes a list and returns a plain english comma delimited string with the items in it. For example, {commas:{mklist:Tom,Dick,Harry}} will return "Tom, Dick and Harry". If you specify the lastsep argument, you can replace the "and" with something else, such as "or" to get a result like "a, b or c". Note: You need to be careful to include spaces around the "or" or else you might get a result like "a, borc". Example: {commas:{mklist:a,b,c}, or } If the var and expr arguments are passed, then for every item in the list, it will set the value of the given variable name (which it will declare) to the item, then evaluate expr, and use the result in the string it outputs. Example: {commas:{contents:here},\, or ,v,{name:{&v}}} will return the name of every object in the room in a comma separated list, using ", or " as the final conjunction. ie: "Tom, Can of SPAM, Dick, or Harry."

Returns true if the string passed to it is a valid number.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns true if the string passed to it is a valid dbref.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the version string for the server.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Returns the muck name string. Example: FurryMUCK
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
Runs the given MUF prog with the string arg on the stack. This returns the top stack value when the prog exits. If the MPI code was run from a propqueue like _listen, or _connect, then {muf} cannot run a MUF program with a mucker level of less than 3
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
This will show MPI debugging information for all the commands within the given expression. This is useful for seeing why something isn't working. This returns the result of the evaluation of expr.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
_msgmacs/div_rand:{add:{div:{:2},10},{dice:{:1}}}
And you had some MPI code that looked like:
{div_rand:22,160}
Then the macro would expand out to:
{add:{div:160,10},{dice:22}}
After the macro argment substitution is complete, it is then evaluated.
Return to the TinyMUCK Page, the Contents, the Topic Index, or the Alphabetic Index.
This effectively defines a function in MPI, with the given name, that takes the given named variables. The function is not immediately evaluated, so it needs to be invoked later, to do anything. Here's an example:
{func:sqr,val,{mult:{&val},{&val}}}
This defines the function 'sqr', that takes a single argument. That
argument is stored in the 'val' variable. The function will multiply
the value of the number passed to it, by itself, returning the result.
It's invoked like:
{sqr:10}
Effectively, the above {func} declaration is the same as the following
macro, and in fact, it's internally handled the same way:
_msgmacs/sqr:{with:val,{:1},{mult:{&val},{&val}}}
You can define a function that takes more than one argument, but the maximum
number of args you can pass to the function is seven. Example of multiple
arguments:
{func:names,list,numsp,flagsp,
{parse:v,{&list},
{name:{&v}}
{if:{or:{&numsp},{&flagsp}},
{lit:(}
{if:{&numsp},{ref:{&v}}}
{if:{&flagsp},{flags:{&v}}}
{lit:)}
}
}
}
{names:{contents:here},1,1}
