Yes.

Delaying until it's value is equal to zero.

Yes.

So it's not more arexx knowledge than you have, not now :)

The other way to do it is to use environment variables, but you have
to use an extra library to use those easily in arexx. So clips are
easier, although they use slightly more memory. The other thing to
watch for with get/setclip is that the clip name is case-sensitive.

Isn't it a bit unnerving that doctors call what they do "practice?"
