The simple version of the code would be:

Dow %scan( '~' : SPdetl : PosLastDelim + 1) > 0;

But of course that would not give you access to the current value. If you need p then it has to be two separate operations - RPG cannot combine an assignment with a condition as you can do in some other languages.

You absolutely can in RPG: you just have to define a procedure that
both returns a value AND modifies its parameters. That was the whole
point of Chris's suggestion.

Personally, I think this is not a good use of procedures (the
avoidance of one line of idiomatic RPG code). Even if you use this
kind of loop all over the place (so that you achieve a net savings in
lines of code), to me this amounts to fighting the language.
