What does NOTIFY=&SYSUID mean?

Question

What does NOTIFY=&SYSUID mean on the first line of a JCL? For example in the below declaration:

//DEV1000D JOB (0998,DEV,000,US),'TEST',        
//         CLASS=D,MSGCLASS=V,NOTIFY=&SYSUID      

Answer 1

NOTIFY=&SYSUID indicates that the user who submitted the job should be notified when it completes.

From the MVS JCL manual: NOTIFY:

In a non-APPC scheduling environment, requests that the system send a message to a userid when this background job completes.

&SYSUID

The system replaces &SYSUID with the user ID under whose authority the job will run, which is normally one of the following:

• The USER parameter from the JOB statement, if specified, or
• The user ID from which the job was submitted.

Answer 2

Let me explain what is NOTIFY

NOTIFY statement is to direct the system ,where it has to send the success failure message after completing the job.

syntax :NOTIFY=userid/&SYSUID

Simply it says to which user the notification has to be send &SYSID is the userid from which the jcl is submitted

eg: NOTIFY=TRC033 will send success/failure message to trc033

NOTIFY=&SYSUID will send send/failure message to user submitting the job
