That's a good point; I've made a note to look into it. This might also be a good candidate for the forthcoming standard library, which will consist of a set of #Include files distributed with the program (and each documented in the help file).AutoHotkey could make the whole process a lot easier by having more information in the Help files on how to use VBScript and JScript in AutoHotkey for example.
CMDRET is still planned, but a lot of things keep slipping in front of it in terms of priority (lately, some of those things are improving the reliability of hotstrings, MouseClick, Send; and adding more GUI control types). To Corrupt: I apologize for procrastinating so long.I think CMDRET should be integrated into AutoHotkey and specific syntax for handling syntax from other scripting languages, like an "OtherScript" command (as oppose to just Fileappend), are needed.
