Hey,
at the moment I have to develop my first CICS transaction on z/VSE 6.1. So I was looking for some examples how to handle Input and Output BMS screens. And I found some tutorial of some german university:
padme.informatik.uni-leipzig.de/de/tutor_z/tutor03b.pdf
But this COBOL example does not seem to work for me like I understood till now.
They are sending Input map and on next statement they already do MAP RECEIVE. How this can work? They will receive same MAP which they sent before or I am wrong?

| What other map would you expect to receive? You send a map to the terminal, the user does something (enters data) and presses an aid key to let CICS know that that user has finished. The program receives the map back with the user's data (or whatever). |

| Do you know the difference between conversational and pseudo-conversational transactions in CICS? If not, you need to do some reading in the manuals. |
