Hello Scott!

I thought, that this would be done at program initialization of the calling
procedure lately???

>     4) 65537 bytes of data are copied from #RtnStr to the caller's

Why that?? When the storage for the return value is allocated before the
procedure is called and only a few characters have to be returned?

I've debugged the calling procedure and set #str1 to a larger string then
the test-string before my procedure was called. After returning from
procedure 2 displaying field str1#  in hex-mode shows, that only bytes in
length of the return-string are overwritten instead if 65535 bytes...

And....using a RPG builtin-function with long varying length fields doesn't
need so much time to perform.
