Music Scales Program

I posted this program (with a few cosmetic differences) to
rec.music.makers a couple of months ago. Since our newsfeed is
now 100%, it seems appropriate for me to put it in alt.sources.
This program generates a list of scales or chords that can be
used for practice. This can be an excellent help for people who
are trying to solidify their familiarity with scales and chords
say, for jazz improvisation.
It has compiled properly on VAX/VMS, Suns, and Microsoft C 5.1. I
would be surprised if their were any significant porting problems
to other hosts.
Enjoy...
