JCL - In-Stream Procedure

Let's see an example to understand In-Stream procedure,

Example 1:

//TESTJCL1 JOB 100,CLASS=C,MSGCLASS=Y,NOTIFY=&SYSUID
//*
//INSMPROC   PROC                   //*START OF PROCEDURE
//PROC1		EXEC PGM=SORT
//SORTIN	DD DSN=HLQ.FILE.INPUT,DISP=SHR
//SORTOUT	DD DSN=HLQ.FILE.OUTPUT,DISP=SHR
//SYSOUT	DD SYSOUT=*
//SYSIN		DD DSN=HLQ.APP.CARDLIB(SORTCARD),DISP=SHR
//           PEND                   //*END OF PROCEDURE
//*
//STEP1      EXEC INSMPROC
//*
//STEP2      EXEC INSMPROC

Explanation:

In the above example, the procedure INSMPROC is called in STEP1 and STEP2.

As discussed in previous chapter, An in-stream procedure INSMPROC coded begin with a PROC statement, end with a PEND statement.

Also, If the called procedure is an in-stream procedure, the system retrieves it from the job input stream. You must place the in-stream procedure before the EXEC statement that calls it.
