The question is, how many people actually need process control when scripting? It doesn't seem to me like a common scripting task. Common tasks make sense to add to mIRC.. less common ones are perfectly okay when left as one-line snippets people can import when needed.
I'm not a big fan of clogging up the global space. Adding an extra identifier would break any script already using some custom $pid identifier since identifiers can't be overloaded like /commands can. I don't get what the advantage of putting this in mIRC is? Unlike the poster above, I disagree that all (most) feature suggestions here can be scripted.. Most of the valid feature suggestions I see are ones that extend the language to allow scripters to do things they could not; I'd rather see more of those.
