I have a doubt in my mind since long time. Can anyone help out?
Only while using Sort/Merge/ICEMAN utility we use
SYSOUT DD SYSOUT = *
What is the specific reason? |

From MVS/QuickRef 6.0:

SYSOUT DD:
This DD statement is required because DFSORT messages are written
to this file. You can override the SYSOUT DD statement to another
DD name using the MSGDDN= JCL parm.

Does that answer the question? |

Universe,
I'm not sure what you're asking.
If you're asking why you need the //SYSOUT DD statement, it's because DFSORT uses SYSOUT by default as the ddname of its message data set (this can be changed with the MSGDDN=ddname parameter).
If you're asking why you would use SYSOUT=*, it's because the * means to use the same output class as the MSGCLASS parameter. You could use a specific message class instead such as SYSOUT=A.
If you're asking why only DFSORT requires a SYSOUT DD statement, it's actually NOT the only product that does. While many products use SYSPRINT, others use SYSOUT, and others use another ddname. It's up to each product to define the ddnames the product uses.
If your question is something else, please state more clearly what you want to know. |
