Wouldn't it also be a viable workaround to have the community-supplied
program (in your example) return the result via HPCIPUTVAR to HPRESULT
or another variable that might have been named via the INFO string? It
could then be used in expressions for IF, WHILE, etc.

Don't get me wrong. The CI enhancements like function results would be
nice, but I suspect that the effort might be high and maybe they would
only be provided as patch for the very latest MPE version(s), whereas
relatively "straightforward" workarounds could be used in all versions.
