Switch Processing

If the TCF user issues any form of the SWITCH command, perform the following steps:

1. Move the name of the session descriptor to UCE-SESSION-DESCR-02.
2. Save program variable storage as either a scratch or a queue record using the site-standard session descriptor as the scratch or queue ID.
3. Perform the following steps:
   • If no task code or product code is specified, move spaces to UCE-NEXT-TASK-02.
   • If a task code or product code is specified, move that code to UCE-NEXT-TASK-02.

     If the TCF user specifies the NEW option of the SWITCH command, move 'N' (new) to UCE-NEXT-TASK-FLAG-02; otherwise move 'O' (old) to UCE-NEXT-TASK-FLAG-02.

     Note: If the TCF user specifies new, you may need to pass data to the switched-to task using either the UCE-INPUT-POINTER-02 or UCE-ENTITY-OCCURRENCE-02 fields in the UCE or some other site-standard convention.

4. Issue a DC RETURN statement.
