How to get multiple PIDs

[Timothy Wynn]

Hello,
I've recently joyed your list. I've tried looking through the archive, but there seems to be no real way of searching the entire 
archive as far as I can tell.

Is there a way to get multiple PIDs at once? For example, if I wanted to do something like:
get_iplayer --nocopyright --fatfilename -w --pid XXX YYY ZZZ

I've tried putting them in quotations, separating them with commas, and a few other methods I don't recall. SO is there any way of 
doing this?

Have a great weekend,
Timothy
