PURPOSE: Cause RAM Compression under OS/2 2.x.

 NOTES:
 - The program will report a size that the swap file grew to when it ends.
   However, the swap file may actually grow larger after the program reports
   it's findings.  This is normal.
 - Before running this program, you should be sure there is sufficient room
   for the swap file to grow by approximate 2-6MB.
 - The location of the swapper file MUST be customized for each system in
   order for this to work.  This is done because on some systems, there can
   be more than one SWAPPER.DAT file due to not deleting the old one after
   changing CONFIG.SYS to point to a new location.
