NOOP Operation
NOOP lets you transmit a dummy UOW to TISERV and receive a dummy response.
The data transmitted in the UOW is returned without modification in the response.
To help identify all IPC messages that are logged, you can use the NOOP UOW to
include, after every IPC header, client data that identifies the source of the transaction.
As an example, you can replace the NOOP-DATA structure with the following DDL
definition; upon receipt by TISERV, this optional data is echoed back to your
application:
02 client-info.
03 application PIC X !(N)!.
03 module PIC X !(N)!.
03 func-code PIC X !(N)!.
03 term-id PIC X (15).
03 filler PIC X.
This definition provides the following tracking information:
APPLICATION contains information that helps identify your application.
MODULE is the SCREEN COBOL program unit code name.
FUNC-CODE is the related transaction (function key) code.
TERM-ID is the terminal ID of the correspondent.
