IST1033I
uservar ALREADY DEFINED FOR APPC SESSIONS OF applname

Explanation

VTAM® issues this message in response to a MODIFY USERVAR command when APPC=YES is specified and uservar has already been defined for applname. Another USERVAR with APPC=YES cannot be defined for this application program.

uservar is the name of the USERVAR which is currently defined for this application program.

applname is the name of the application program specified in the MODIFY USERVAR command.

System action

VTAM rejects the command and no changes are made to the USERVAR table. Processing continues.

Operator response

Determine which USERVAR should be defined for the application program.
  • If the currently defined USERVAR is incorrect, you must delete the currently defined USERVAR with a MODIFY USERVAR,OPTION=DELETE command. After deleting the incorrect USERVAR, issue a MODIFY USERVAR command to define the correct USERVAR for the application program.

    If applname’s ACB was open while the incorrect USERVAR was defined, then the incorrect information was copied to the application program’s control blocks. In this situation, VTAM issues message IST1034I when the MODIFY USERVAR command is entered for the correct USERVAR.

  • If the currently defined USERVAR is correct, no action is required.

System programmer response

If the MODIFY USERVAR command was issued through the program operator interface, determine which USERVAR should be defined for the application program and correct the mechanism that established the incorrect USERVAR definition.
