MAI Installation Exit MAIEX02 › How You Implement the MAI Exit › Reentrant Code

Reentrant Code

You must write the exit to conform to the following rules:

• It is written in reentrant code
• It does not modify any storage location within itself
• Any working storage required other than that provided in the communications area is obtained using GETMAIN.

Failure to observe these conditions will result in an abend in the processing task and the session request will fail. Other processing is unaffected.
