If you're in entrymode, I think it would automatically reprompt that field, and
re-call your input procedure with the bit after the semicolon (hence the else
clause above). If you're not in entrymode, you probably need 'push id N' or
something. Powerhouse has two field inputs queued up: the (null) part before
the ';', and the part after the ';', you just have to construct logic so that
it prompts for them in the right field.
