$ifmatch
From Scriptwiki
Returns the first parameter of an if-then-else comparison.
$ifmatch
Note: $ifmatch is depreciated now and has been replaced by $v1 and $v2. You should switch to using $v1 and $v2 incase $ifmatch is no longer supported in future versions.
$v1 & $v2
These return the first and second parameters of an if-then-else comparison.
$v1 $v2
Example
if ($me isin $read(quotes.txt)) { echo -ag My nickname is in random quote: $v2 }
In the above example we check if $me is in the text returned by $read. If the comparison is sucessful $v2 is set to what ever $read returned.
