I think the easiest way is to ctrl-f all your scripts for that %variable and put
/run file.exe after the places where it gets set...
Another alternative would be making your own alias set, check for the variable and if it's the one you want, do your stuff. Don't forget to actually
set $1- in your alias body and don't be surprised if most of
your scripts don't work anymore... At first glance I noticed that all /var stuff will be broken.
//!var won't work,
//!set -l might...
when i type a command like !word Mynick blah
use
/word blah and put something like this in remotes:
alias word { run file.exe $me $1- }
