Re: CL arithmetic -- conclusion

There was a discussion a while back about using a keyword on the F-spec
to do the override. Seems like the response to this was favorable from
the IBMers and non-IBMers (my memory has been known to be faulty at
times <g>). Does anyone have any scoop on the timeframe for the next RPG
compiler release and what we can expect to see? Haven't heard anything
lately.

As far as doing the CL commands inside RPG, I do that as much as
possible myself. Just wished that I could use RTVxxx commands in RPG and
get the variable returned.
