There are compilers other than RPG???  <G>

Seriously, I was thinking strictly in terms of VALUE with no other
significant keywords because, other than a couple of multi-module
multi-language service programs, all of the procedure calls where I
work are ILE RPG to ILE RPG.

And even in the multi-module multi-language service programs, the
non-RPG procedures are not exported, they are called only by other
procedures in the service program.  And none of them use parameter
types and sizes that are susceptible to the cross-language problems.
