Mainframe, MVS and zOS Discussion

Hi,

I've a CICS program in which there is a value which I'm writing to TSQ. This value I need on next 'start' of the program but some where in the program this value, which is a flag, is getting lost when I read the TSQ again. Ideal logic is that I figure out that why data in TSQ is getting initialized. But in parallel I wanted to check if I can store this flag's value somewhere to see if the logic I want to apply is working or not. How can I do this?

What do your WRITEQ TS and READQ TS statements look like? Without seeing them, there's not much anyone can do to help you.

But in parallel I wanted to check if I can store this flag's value somewhere

Assuming you mean other than in the TSQ, the usual and common method to pass data between programs is to use DFHCOMMAREA or a container / channel depending upon your level of CICS.

Hi Robert,

Thanks for the answer.

Please allow me some time and I'll post the required information. We have recently upgraded to CICS v5.5 and I have been told that it supports container / channel. I am not very familiar with this concept and I did some reading online about it but I don't feel like writing a program with IBM manuals I read. Is there a 'getting started with container / channel' document you know, by chance?
