AdiIRC

Added in 1.9.0

$adiircexe

Returns the full path and filename of the AdiIRC executable file.

In combination with $~ this can be used to test which client is running the script. You cannot assume the client name based on the filename.exe, but instead testing whether $adiircexe exists as a built-in identifier. The $~ prefix allows the test to evade the presence of a custom alias of that name, and it also does not trigger the optional identifier warning.

//if (!$~adiircexe) echo -a this script is not running in AdiIRC

Can be used inside text.
