I have a jcl which is using 2 data sets i want to override those data sets. how can i override the files within the JCL. Give me the syntax. Make sure that it is not calling any Proc.
Answer / indira
Hi... Make sure your que is correct
Acc to what I understood from ur que u want to give the override of the 2 dataset in the same jcl itself...if this is the case then make use of symbolic parameter.
In the jcl above before executing the steps use SET parameter to give the name for the override dataset.
For eg -
//SET1 SET HLQ1 = High1
// HLQ2 = High2
....
//DD1 DD DSN= &HLQ1.DS
//DD2 DD DSN =&HLQ2.DS

Suppose a proc step has a DD statement like //ABC DD DSN=TEST.FILE1,DISP=SHR DSN=TEST.FILE2,DISP=SHR and the above DD name is overridden from the JCL as given below //procstepname.ABC DD DSN=TEST.FILE3 - Will the DD statement now have just TEST.FILE3 or it will be TEST.FILE3 and TEST.FILE2? Suppose if it is overridden twice like //procstepname.ABC DD DSN=TEST.FILE3 //procstepname.ABC DD DSN=TEST.FILE4 Will this give a JCL error? If not, what will be final output?
how to override PROC? please give answer in details. Please mention how to write it in JCL. Thanks in advance.

My JCL has 4 steps that execute PROC’s P1, P2, P3 and P4 as shown below //P1 EXEC PROC=P1 //P2 EXEC PROC=P2 //P3 EXEC PROC=P3 //P4 EXEC PROC=P4 There are four steps S1, S2, S3 and S4 in each PROC’s (i.e. P1, P2, P3 and P4) I want to execute only step S2 of PROC P2 and no other steps or PROC’s. How do you achieve this?
