EXCPW Prolog
 Name       : EXCPW
 Description: VSE EXCP Work Area
 DSECT      : EXCPW
 Function   : EXCPW is a work area used exclusively by module
              DMSXCP. DMSXCP is the CMS/DOS module which
              handles the EXCP (Execute Channel Program)
              macro. EXCPW is pointed to by IJBCCWT in
              SYSCOM. The mapping of EXCPW is called by
              issuing the EXCPW macro with the DSECT
              parameter.
