REXXUTIL demonstrates a set of external functions packaged in a dynamic link library, including:

• Use of OS/2 system functions in REXX external functions
  
• Techniques for passing large amounts of data to a REXX program using REXX compound variables as arrays.

REXXUTIL runs on 32-bit OS/2. It can be run in an OS/2 full-screen session, an OS/2 window session, or in PMREXX.
