While that is true, I don't think anyone is talking about a "copy" op code. :-) I had thought about mentioning in the software part of the argument that COBOL actually has a "move" verb to accomplish that, i.e. "Move A to B." even though you are technically right that it is a copy. -- - Stephen Fuld (e-mail address disguised to prevent spam)
