This exit allocates several datasets required to communicate between the user’s ISPF environment and ChangeMan. You must allocate
all required libraries of your ChangeMan subsystem, such as LOAD libraries and the ChangeMan Parmlib.
Note: This is a sample REXX procedure only. It is not called automatically in the ChangeMan Attachment. Call this procedure in the
REXX routine TAUTOXA1 if you want to use dynamic allocation of the ChangeMan datasets.
