Hi,

We are working on a strtegy to convert from NATURAL/CICS to COBOL/CICS (Conversational to Pseudo conversational).
Has anyone worked on Conversational to Pseudo conversational appraoch conversion before?. If yes, please suggest some tips on how to retain the working storage values after performing the SEND MAP.

Thanks,
Selva.

Usually the DFHCOMMAREA is used to preserve values between transactions. The first transaction has to define the DFHCOMMAREA from working storage. Make sure that you use the DFHCOMMAREA properly, otherwise you can jeopardize your CICS stability.

Hi Selva,

You can also look at making use of Temporary Storage Queues (TSQs), to hold the data, that can be read across transactions.

You need to evaluate all the options based on the requirements on hand. For instance, do you need to develop a generic strategy for achieving the desired feature, or is it program specific.

If you would need to store paging data, then TSQs are definetely the way to go forward.
A sample example is illustrated below:

The first program fetches all data (based on the inputs from the search screen) and writes into a TSQ and invokes the second program, which would then usually display the retrieved data as a list, reading from the TSQ and terminate. Based on the user input, the second program would then interpret the input and act accordingly.

Hope this helps.

regards
himesh

Thanks Himesh.

The requirement is to develop a generic strategy. I am also thinking to use TSQ more in this approach. Now I am collecting details on the limitations of using TSQs.

Regards,
Selva.

could someone provide a simple example of a pseudo conversational program?

a pseudo conversational program is indeed a pair of programs? one to send the map and the other one to receive the map and process it?

thanks
