I haven't looked at the Java FOR instruction, but if your collection is a
subclass of Dictionary (e.g., a Hashtable) then NetRexx has always allowed
you to iterate over it using LOOP OVER name.

Hmm, but for those you have a known numerical index .. 'loop i=0 to
whatever' is going to be as fast as anything NetRexx would do, and maybe
as clear, too.

I'm spending about 150% of my time on decimal-related things at the
moment, so don't hold your breath...
