Thanks. I'm not familiar with it. A requirement I forgot to mention is 
that I be able to execute the program under Win. I'm using standard PC 
graphics. No Silicon Graphics machines here. :-)

I edged out of *nix years ago, but may fire it up in a month or two on 
an older PC. About 15 years ago, I put together a program that would do 
the trick that I'm looking for in this instance.
