Re: Bitwise ops in RPG

[Jim Langston <jimlangston@xxxxxxxxxxxxxxxx>]

I would tend to agree, Hans.  If there is already a build in MI
instruction that you can use similar to a BIF no need to make a
BIF for it.

Personally, I don't like BIFs, but as someone said, it's a
Florida type majority for BIFs.

Making bit operations infix operators would just appease the small
minority of us who also program in other languages and are used to
those type of operators.  No real business need to do them, less
you got a spare $100 and extra time laying around.

Could someone please point to the documentation on the Bitwise MI
instructions with perhaps a line or two on how to use them?  Thanks.

Regards,

Jim Langston
