Re: Binary variables in RPG

If I remember correctly, I think the original arithmetic instruction sets and "innards" for S/34, S/36 (and CISC?) were designed for packed numeric data, which was therefore faster for doing the math. Meaning to do calculations, convert to packed numeric and back. Checking 32767 limits might put extra overhead on it?

By the way, for the new kids on the block, on the subject, sort of, RPG-III has 80 columns for SRCDTA because the old IBM punch card held 80 columns, and they just kept the "backward compatibity". :-)

Why they original designed the "B" data type that way in RPG III is
completely beyond me.
