SYSTSPRT data sets in REORG PLUS
REORG PLUS always requires the SYSTSPRT data set for REXX exits.
REXX routes all output from the REXX 'SAY' statements to this data set. It is usually coded as a SYSOUT DD statement.
For a MAPTEXIT user exit, REORG PLUS dynamically allocates this DD if your JCL does not include a SYSTSPRT DD statement.
