So it *is* the length of the variable, and there's no need to trim trailing
blanks.

If you code CONST on the parameter, the length shouldn't really be any longer than the prototyped parameter.

But if that might be a problem, the problem could exist even if you do trim the value, since your trimmed command might be larger than the parameter definition.

I think the API documentation goes a bit too far here, since it's implying things about programming languages that might not apply everywhere. It should really just say that it doesn't matter if the command string has trailing blanks.

But anyway, the way ILE RPG works currently for fixed length fields passed to CONST fixed length parameters, where the passed parameter is longer than the prototyped parameter, the compiler just passes the field directly without using a temp, so the whole field would indeed get passed to the API.
