A Step in a JCL creates a GDG version (VB , Lrecl 11004).
How can I implement something as follows after the step ???
If GDG-ver %Used > 0
TSO SE 'Records created' U(TESTID)
End-if
Basically a User should be notified automatically in someway that records were created , without having to check the Job output .

Vini,

If I understand correctly , you want to send a message to the user if the file has atleast 1 record. You can use one of the methods shown in the link below to check for an empty file and use the retun code to send the message.

http://www.mvsforums.com/helpboards/viewtopic.php?t=1285&highlight=empty

for ex: if you used idcams to check for the empty file , then the next step will run only when there are records in the file.

Code:

//*********************************************************************
//* SETS RC=0000 IF DATASET HAS RECORDS *
//* SETS RC=0004 IF DATASET IS EMPTY *
//*********************************************************************
//EMPTY EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//FILE01 DD DSN=YOUR FILE IN QUESTION,
// DISP=SHR
//SYSIN DD *
PRINT INFILE(FILE01) CHARACTER COUNT(1)
//*
//SENDMESG EXEC PGM=IKJEFT01,COND=(4,EQ,EMPTY)
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
SE 'RECORDS CREATED' U(USERID)
/*

Hope this helps...

Cheers

Kolusu

Kolusu, Can I use these Steps ,as the Last two steps if I make them a part of the same JCL in which the File is created ?!
My concern is , would the Record count be available in the same JCL after the Step in which the file is created. I want to confirm this , vaguely remember coming across some Posts where these things seemed to be a concern (maybe in a different context though).

Vini,

Yes you can use these steps as the last steps of same job which creates the dataset. Make sure to give (+1) version for the last step also. check this topic which explain more about using newly created gdg version in the same job.

If I understand correctly, it means the GDG gets catalogued soon after the last successfully executed step of the JCL.
