Re: Can we access extra partition TDQ from Batch?

A good example of extra TD usage are the CICS log queues like CSSL and CSMT (if memory serves) which are usually mapped to extrapartition queues for processing by CICS batch utilities.

Re: Why DataSet restricted to 44 characters on zOS?

IBM invites 44 finalists to the inaugural Master the Mainframe World Championship http://www-03.ibm.com/press/us/en/press ... /43308.wss. Surely that's not a coincidence.

Re: How CICS works?

The question "How CICS works?" is certainly pretty broad. Robert's reply gave you some insight into 3270 task initiation, but you'll find a lot more interactions covered in these two IBM Redbooks: CICS Transaction Server from Start to Finish http://www.redbooks.ibm.com/abstracts/sg247952.h...

Re: Why DataSet restricted to 44 characters on zOS?

It's probably not coincidental that 44 characters give you five octets separated by periods. You also need to bear in mind the limitations of the original JCL input media - 80 column punch cards.

Re: How IMS work along with CICS?

I think the best place to start would be by reading the IMS Database Control Guide available in the CICS infocenter http://pic.dhe.ibm.com/infocenter/cicst ... t4_pdf.pdf
