submit a job using a cobol program and using CICS.

[Niketan]

This is a question I could not fully answer. It had two parts.In first part, interviewer asked me if we can submit a job using COBOL program? And in second I was asked if we can do the same using CICS program too? 

The further question was, what is the way of doing these two?

For COBOL, I replied that we can execute a Job using the utility INTRDR. But I had nothad any idea about running a JCL from CICS. Can we do that, please tell me?

 For CICS, if a TD queue is defined pointing to the internal reader you can write JCL statements to it.

Just being nitpicky - INTRDR should not be called 'utility' ...or should it be?

[Robert Sample]

The z/OS JES Application Programming manual refers to it as a "logical device".  I don't think it can really be called a utility since utilities are executable programs and a logical device is not an executable program.

Thanks Robert. It's always fun to have you around! Appreciate your time!

Thanks Robert. Can TSQ also be used for the same purpose?

Thanks guys, have not thought it like that.

No.  A temporary storage queue points to a location in memory -- either main memory or auxiliary memory.  A transient data queue points to a DD name that CICS manages; that DD name is usually DD SYSOUT=(A,INTRDR) to allow internal reader job submission from within CICS.  You could also use EXEC CICS SPOOLOPEN / EXEC CICS SPOOLWRITE / EXEC CICS SPOOLCLOSE to write directly to the JES spool, assuming you're using a reasonably recent version of CICS.

Thanks for the explnation. It is really helpful.
