Ezio, compulsory means something like required. Your sample shows an
simple copy and then a DUMMY is enough to accomplish the task. At the moment some editing is needed a SYSIN is needed. The TS didnt supply that kind of information. |

Take out the SYSIN. Run the step. There's your answer. You can try it several times, just to be sure, but the answer will be the same.
Why are you asking? |

Yes, It is mandatory. I just tried to run the utility without SYSIN parameter and got RC12 with below error.
DATA SET UTILITY - GENERATE
IEB316I DDNAME SYSIN CANNOT BE OPENED
Sigh, the utility needs a SYSIN, it can be DUMMY for a straight copy, if not you supply parameters with it. Maybe the TS AND jalsaking1
consult the manual.

There are no "views" or "opinions" on this -- either IEBGENER requires the SYSIN DD statement or it does not; this is called a FACT. And the fact is, IEBGENER will not execute any copy if the SYSIN DD statement is missing -- as was mentioned, it will set return code 12 and stop processing. |

| The section of the manual that deals with IEBGENER, or any other utility for that matter, explains what JCL is required and when. |

I also share the same thoughts as of Bill - why do you ask this question?
The basic IEBGENER JCL is:
| Code: |
//JS10 EXEC PGM=IEBGENER,REGION=1024K
//SYSPRINT DD SYSOUT=* Messages
//SYSUT1 DD DSN=...,DISP=... Sequential Input File
//SYSUT2 DD DSN=...,DISP=... Output File
//SYSIN DD * Control Statements
control statements...
/* |
SYSIN is needed for your control statements. You just don't provide DUMMY on SYSIN, there are many other control statements which can be used. Well, 'gain your question is confusing.
Is it an interview question, by any chance? |
