Returns the first parameter of an if-then-else comparison.
Note: $ifmatch is deprecated and has been replaced by $v1 and $v2. You should switch to using $v1 and $v2 in case $ifmatch is no longer supported in future versions.
$v1 & $v2
These return the first and second parameters of an if-then-else comparison.
The above example is a snippet that could be used inside an On ban event, which will check to see if the ban mask set matches your host mask. If the comparison is successful $v2 is set to your IAL's host mask.
