Here is my JCL command
someone please help me why i got this error message, i got so frustated
There might be a few issues here, depending on what you're trying to do...
First is the issue mentioned by Fritz - you need a space after "JOB". The TSO submit command parses the JCL you submit, and if it thinks there's no JOB statement, it automatically generates one for you based on the information associated with your TSO session. You can see in the JCL that this is the case.
A little tidbit of information here is that if you're happy with the JOB statement generated by SUBMIT, then you don't need to include one in your JCL...no reason your JCL couldn't just start with the // EXEC PGM=IEFBR14 line. Sometimes this is done so that different users can submit the same JCL without needing to alter the JOB statement information.
Second, your question says that you're trying to create a partitioned dataset, but what you have coded is a sequential file. If you really mean to create a PDS, then you'll need to make two simple changes:
One final comment is the RLSE...since IEFBR14 doesn't actually open the dataset you just created, RLSE doesn't really do what you expect. The typical use of RLSE is for programs that create files of varying sizes...you tend to set the allocation to the largest you expect, and RLSE trims back to the nearest extent should you write less.
