Thank you for these scripts.. apreciate this! But take in view that many commands from mirc can be replaced with these kinds of scripts (using $com or even VbScript) you provided as examples! No many people know $com objects and all this, but we like to make these all ideas simple
P.S. $isadmin alias you provided not works, because is not tell if mirc.exe what is running it runs with admin right or not, it tells if you have admin rights in the system.
P.P.S. /run -h or /run -np also can be replaced with the commands you provided, $os - also and more others..
