if i provide DISP=(NEW,CATLG,____) then what would be the value in the third attribute ?
Would it be CATLG same as of 2nd attribute or DELETE as first attribute is NEW ? |

| What would you want the disposition of that dataset to be if that job step failed? |

There is a link to manuals at the top of the page. The JCL Language Reference manual says
| Quote: |
12.19.3 Defaults
If you omit the status subparameter, the default is NEW.
If you omit the normal termination disposition subparameter, the default is DELETE for a NEW data set or KEEP for an existing data set.
If you omit the abnormal termination disposition subparameter, the default is the disposition specified or implied by the second subparameter. However, if the second subparameter specified PASS, the default abnormal termination disposition is DELETE for a NEW data set or KEEP for an existing data set.
If you omit the DISP parameter, the default is a NEW data set with a disposition of DELETE for both normal and abnormal termination disposition. Thus, you can omit the DISP parameter for a data set that is created and deleted during a step.

Why are you not looking this up yourself? |

And the JCL manuals neglect to mention this? After 50 years of JCL?
And this cannot be tested in 5 minutes?
Do you want to learn how it works, or just try to remember what someone else (who might be equally lazy and just guessing) said about how it works?
Wow! |

Only if you could look at the JCL Referecne Manual:
| Quote: |
Syntax:
{DISP=status}
{DISP=({status}{,normal-termination-disp}{,abend-disp})
Defaults
- If you omit the status subparameter, the default is NEW.
- If you omit the normal termination disposition subparameter, the default is DELETE for a NEW data set or KEEP for an existing data set.
- If you omit the abnormal termination disposition subparameter, the default is the disposition specified or implied by the second subparameter. However, if the second subparameter specified PASS, the default abnormal termination disposition is DELETE for a NEW data set or KEEP for an existing data set
- If you omit the DISP parameter, the default is a NEW data set with a disposition of DELETE for both normal and abnormal termination disposition. Thus, you can omit the DISP parameter for a data set that is created and deleted during a step. |

Good reply. Let us know what you find. You are taking a major step toward ownership. |

Defaults are good-ish ... me if I can control I will ( yeah the cost of therapy is crippling )
Job runs and fails - new file is a) scratched or b) cataloed ????
If its an App producing a report a) is good
If its DB2 reorg a) is bad
JCL is dumb ... it's down to you to make things happen - defaults are for the lazy (or dim!) |
