IEBEDIT(Edit Job stream) Utility:

1. It is used to run selected job step(s) in particular JCL.

Ex. I have a JCL with 10 steps and wanted to run only STEP10, 

//IEBEDITX JOB (MVSQuest),'IEBEDIT TEST',
//            CLASS=N,MSGCLASS=H,NOTIFY=7SYSUID
//*
//SUBMIT   EXEC PGM=IEBEDIT
//SYSUT1   DD DSN=USERID.TEST.JCL(JCLINP),DISP=SHR
//SYSUT2   DD SYSOUT=(*,INTRDR)
//SYSPRINT DD SYSOUT=*
//SYSIN    DD *
 EDIT START=JOBA,TYPE=INCLUDE,STEPNAME=(STEP10)
//*

JCLINP contains 10 steps

START => specifies job name of JCLINP

TYPE=INCLUDE => runs only those steps specified in STEPNAME

If TYPE=EXCLUDE, it runs all the steps except for the one specified in STEPNAME

If i want to run step09 and step10, then

EDIT START=JOBA,TYPE=INCLUDE,STEPNAME=(STEP09,STEP10)

2. Copies the complete job including all its steps to the output data set
    
    EDIT START=JOBA

3. Copies different steps from different jobs to output data set
    
    Example: If i have 3 jobs (JOBA, JOBB,JOBC)  in input dataset and wanted to copy different steps from all the 3 jobs

EDIT START=JOBA,TYPE=INCLUDE,STEPNAME=(STEPC,STEPD)
EDIT START=JOBB,TYPE=INCLUDE,STEPNAME=STEPE
EDIT START=JOBC,TYPE=INCLUDE,STEPNAME=STEPJ
