When you say "without", do you mean without setting pm->level at all?
That wouldn't work because a level is only assigned if you "typeset" or
equivalent --- a normal assignment creates a global parameter.  But I'd
expect it to work with locallevel instead of locallevel+1.

I don't understand the difference if createparam() isn't there.  It
should always be called by any function that needs to create a parameter.
