VARPOOL -- An example of how to fetch and set REXX variables
------------------------------------------------------------

To run:

    varpool macroname [argstring]

A simple macro, TEST.CMD, has been provided, so just type:

    varpool test

To try it out.


Notes
-----

This program defines some external functions that are then called
by TEST.CMD.  Inside those external functions we muck around with
the variable pool.

Routines to set and get variables are found in VARPOOL.C.
