Umm.... *Bangs head against wall repeatedley*.

I'm not normally that stupid. Really. ;-)
I guess I was so absorbed with trying to work out what was wrong with the
function call/ expression in the brackets that I didn't notice the typo.
(Since it wasn't in the original handwritten listing, I can get away with
calling it a typo. Well, that's my excuse, and I'm sticking to it :-)   ).

Seriously... thanks to everyone who spotted that. Sometimes it needs a fresh
eye to spot an obvious error that's been overlooked, like that one.

While I'm here, see what you think of this "Celestial Fireworks/ Globular
Cluster"  program :-
ftp://ftp.simtel.net/pub/simtelnet/msdos/astronmy/glclu12.zip

It's not all mine (being based on a BBC BASIC listing!), and don't expect
technical brilliance either- since it was written as a programming exercise,
it doesn't exactly show off Allegro's capabilities. In spite of all that, it
has a certain appeal (I hope!)- and the source is there to hack around with
if you want...
