I think it would be quite useful to have a $run identifier, which would return $true/$false depending on if mirc can /run a file or url.
For example:
if ($run(notepad)) { run notepad }
Rather than using $isfile or $exists (which wouldn't work on 'notepad' anyway) - this identifier would only see if $1 could be /run
I hope my point is being made and maybe someone will agree with me
Thanks for the word,
