I "sorta" agree with this. I don't like to rely on
global variables either, with one very pronounced
exception. I do set up my PostScript output (via
PS_START) with global variables for plot thickness,
character size, font selection, etc. It is just so
much easier to do it this way.

Cheers,

David
