Well, I'll do something like xargs that allows a bunch of parameters, just not all of them, or use "p4 -x -" syntax and pipe the parms in to it's stdin. The only reason I hesitate to use that syntax is that I don't know how long ago it was introduced and I want to be pretty backwards compatible. It was there in 99.1, at least, so I guess I'll use it and go to an xargs-like invocation loop if somebody reports problems.
