Re: Decimal versus binary arithmetic was Re: J4 - presentation/discussion on "Fu

Clark,
Can you try this (slight) variation - and compile

01  numerator value 1 Comp-5 pic 9(9).
01  denominator value 5 Comp-5 pic 9(9).
01  quotient Comp-5 pic 9(9)v9(4).

compute quotient = numerator / denominator
display quotient

My guess is that they would still be doing it in decimal, but this would "fo
rce"
the compiler into knowing the fields were to be truncated/handeld in "true"
binary rather than based on the PIC.
