JCL PROCEDURE

PROCEDURE (PROC)

1. Procedure is re-usable component, which consist of EXEC and DD statement.  

2. Procedure are not submitted directly (it can be call).

There are 2 types of procedure

1. Instream procedure

2. Catalog procedure.

Procedure name max: 8 characters and min: 1 character.

Working of procedure

1. Declaration of proc.

2. Execution of proc.

3. Changing of parameters.

INSTREAM PROCEDURE:

                      It is defined within a job, with proc name starting with proc operand.

RULES:

Max 15 instream proc can be defined by one job.

Proc can be executed within in a jcl program in any activity.

Example:

Copying data from one dataset to another dataset.

Creation /deletion of datasets.

Sorting data.

DECLARATION OF instream procedure:

Instream procedure starts with proc and end with pend statements.

Instream procedure should defined, before any exec statement defined.

EXAMPLE:

 // KC03P88E JOB 123,’SANDEEP’,NOTIFY=&SYSUID,MSGLEVEL=(1,1)

//PROC1     PROC

//STEP1 EXEC PGM=IEFBR14

//DD1  DD  DSN=KC03P88.SAMPLE.PS1,DISP(NEW,CATLG,DELETE),
//           SPACE=(TRK(15,10,0)) ,DCB=(LRECL=80,BLKSIZE=800,RECFM=FB,DSORG=PS)

//             PEND

//STEP2   EXEC PROC=PR0C1    ----------------EXECUTION OR CALLING OF proc

//SYSPRINT DD SYSOUT=*

//SYSIN DD DUMMY

        

CATALOG PROCEDURE:

            

 It is defined outside of jcl program, in a PDS member with PROC and no PEND statement .

Catalog proc can be executed in any jcl program, across application .

Any member of catalog proc can be defined.

Important point :

1.Similar to JOBLIB & STEPLIB, PROCLIB must code with a jcl program immediate after job.

2.Catalog procedures are coded in a PDS member

3.Catalog procedure can be executed from any job across application.

4.To locate catalog procedure PROCLIB, system defined DD name be specified immediate.

5.Catalog procedure can be changed by using symbolic parameters.

6.Symbolic parameter: it is user defined name pre-fixing with single amperson (&).

EXAMPLE:
