XCMCMDXT Exit

Use the XCMCMDXT exit routine when a JES2 command is to be issued to perform job requeue processing. The installation user exit can modify the command text when using modified JES2 command syntax.

Upon entry to the XCMCMDXT exit routine, the required command text has been built in the CMDX_CMDTX field of the CMDX_PL parameter list. If necessary, the installation exit can alter or replace the command text in the CMDX_CMDTX field.

The exit can manipulate the command action flags in the CMDX_FLG1 byte. The CONSOLE name and the UTOKEN can be customized (replaced) by the exit; however, the replacement values must be valid. For example, if the XCMCMDXT exit routine supplies a different CONSOLE name, that CONSOLE name must reflect a valid, previously defined MCS or extended MCS CONSOLE.
