Re: Humorous Enhancements

YES!!! YES!!!  We need some real bitwise operations.
(this probably doesn't surprise you coming from me)

I've had to write special routines that go through a string of
bytes, check every single bit with TESTB, compare it against the
same bit pos in a different string, and finally do a manual XOR.
(by checking the result indicators of testb) and then finally
using BITON to set the string of bytes to the result.

Doesnt perform real well when compared to a real XOR operation.
I'm sure the CPU can do XOR at the machine code level...  so it seems
silly to have to go that far to make an XOR. :)

So yeah, I'd love to see better bitwise operations in RPG, and also
to be able to do bitwise operations on integer variables instead of
just on character variables...

Good idea, Joel!
