/set Command - mIRC
< mirc‎ | commands

The /set command can be used to replace the value of an existing variable or create a new variable and assign it the given value. By default /set creates global variable, this can be changed via the -l switch. Unlike the /var command, set cannot assign a value to multiple variables at once. It support one math operation.

Set evaluation routine[edit]

The set command has its own evaluation routine which lets you dynamically concatenate additional values onto the variable name before the assignment takes place.

//set -ls % $+ $ctime ABC

Will create a variable like %1209425041 with the value of 'ABC'; Similarly this can be used with $nick and $chan in on events.

Note: /set will fail to evaluate your variable if you have dynamic parameters before the name, read more here

Synopsis[edit]

/set [-gisuNznelk] <%var> [value]
/set [-gisuNznelk] <%var> <number> <+ | - | * | / | % | ^> <number>

Switches[edit]

  • -s - Display variable assignment value
  • -uN - Unsets the variable after N amount of seconds. A special case has been made for -u0 which will make the variable unset at the end of script processing, the same way binary variables do.
  • -z - Decreases the value of the variable by 1/second until zero is reached. At zero the variable will be unset.
  • -n - Treat the value as plain text, even if arithmetic operators are used.
  • -e - Unsets the variable when mIRC exits
  • -l - Creates a local variable instead
  • -k - Keeps the unset time (-u) from a previous command
  • -i - Only set the value to the variable if the variable does not already have a value, good for initialization
  • -g - Since you can have a global variable and a local variable of the same name, this makes sure the global variable is set

Parameters[edit]

  • <%var> - The name of the variable
  • [value] - The value to assign to the variable
  • <number> - Any arbitrary numerical value, can be a floating point number
  • <+ | - | * | / | % | ^> - One of the six possible arithmetic operations
  • <number> - Any arbitrary numerical value, can be a floating point number

Example[edit]

; /countDown 
Alias countDown {
  ; set some value
  set %var Countdown:
  ; print the value
  echo -a %var
  ; set the value to 3, decrease once per second
  set -zs %var 3
}

Will output:

Countdown:
-
* Set %var to 3
-
* Set %var to 2
-
* Set %var to 1
-
* Unset %var
-

The -u0 switch can be used to create a variable with global scope that will get unset at the end of the script processing. This can be very helpful at times.

Alias example {
  set -u0 %x A
  bb
  ; will print 'B'
  echo -a %x
}
alias bb {
  ; replace the value of %x with B, keep the unset setting
  set -k %x B
}

A simple !seen script that uses /set special evaluation routine to create dynamic variables:

on *:text:!seen &:#mIRC:{
  ; check if the variable is set
  if ($var(seen. $+ $2)) {
    ; notice the user the value of '%seen.<nick>'
    notice $nick I have seen $2 $var(seen. $+ $2, 1).value
  }
  else notice $nick I have not seen $2 anywhere.
}
on *:text:*:#:{
  ; set the value to '%seen.<nick>'
  set %seen. $+ $nick Talking in $chan < $+ $nick $+ > $1-
}

Compatibility[edit]
