... and let me guess.  You want full descriptor, and still be writing V3R2 code?

Point taken.  As I said, I have never had to even come close to that
size in a business app yet (aside from EVAL interim results :), but
that may just be because I don't work with international currencies or
large corporations.

And besides, till I quit coding to V3R2 levels it doesn't much matter.
I couldn't use a float field if I wanted to...

Us too. <g>  (I sure wish Rochester had designed for full operational
descriptor support!)

Personally, I don't see much value is this particular example.  I was
simply trying to show Brian that if he felt it was more readable, that
he didn't have to ask for a BIF then wait for it.

I'm a big fan of subprocedures in general -- they can really add lots
of readability to code when named properly.  And make life alot
simpler in terms of code reuse.  Service programs are great.

But regarding long floats -- is conversion to them an "expensive"
operation?  I'm assuming (bad idea) it is much more so than decimal
alignment of other packed fields, or conversion of zoned or integers.

I suppose a function like IsNegative() would not be likely to be used
heavily enough to even care to benchmark the difference between using
a 30P 9 const argument and a long float.
