File Compress/Expansion routine.
From:  Jeffrey C. Moxon 73561, 1431

        These routines were created using .GIF reading and .GIF writing 
routines.  The original routines are published by McGraw Hill in "Bit-Mapped 
Graphics" by Steve Rimmer.  I have modified the routines from the original to 
be used for minimal file compression and expansion.  The random number 
generator was written by David Stafford of "Computer Shopper" magazine, and 
can be found on Ziffnet (along with many of David's own compression routines 
which compress much better than my own).

        I posted this code in January 1994 (see COMPRE.ZIP), and have made 
some changes to it since, so I decided to post an update.  You may do whatever
you like with it.
