Re: What happens to unused constants?

[Don <dr2@xxxxxxxxxxxx>]

Why would it throw it away?  Let's presume it's a program bug that you
hadn't used a constant and needed it during debug...if thrown away you
couldn't use it...

you can always to a genopt on a program and look at the MI generated to be
sure, but I think it's all kept...kinda like alot of defined but unused
function keys, etc....
