RE: Quick OPM RPG question -- but does my solution have potentialside effects?

Nope,

When you pass by reference, it doesn't matter if you pass 1-byte or 1,679,832; all you are really
passing is a pointer to the first byte.

The only catch would be if you were trying to use operational descriptors, but those don't work for DS
anyway.

Given that the program that's crashing doesn't actually use the MULTDS
it is passed, but merely passes it, if available, to a customized
UNDEL2, and given that everything in an OPM program call is passed by
reference, I tried this:

I changed the optional parameter to a simple 1-character field.

Now, if the MULTDS is received (in the 1-character field), it is passed
on to the custom UNDEL2. If it isn't, it isn't. And it looks like the
custom UNDEL2 is getting the whole MULTDS.

*************

*BUT I'M WORRIED.* This MULTDS can potentially have 9999 occurrences of
186 bytes each. Could there be side effects of passing a reference as if
it were only one byte?
