RE: What happens to unused constants?

The debugger won't let you display CONST's anyway, whether or not they are
in the program... so "keeping them" is really pointless.

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....
