Using CICS 4.1 can be dangerous

I'm attempting to use field level triggers in CICS. This is my first time using this facility. I've read the IBM manuals and I think I have the basic understanding.

In my COBOL pseudo-conversational application program I'm moving the DFHTRIG (i.e x'7F') to my "V" field just prior to sending the map and returning control to CICS. However, when I key in data to my trigger field via the map, the tran does not trigger. What am I missing? We are currently running CICS 4.1. Is there something above and beyond the application that needs to be set up prior to using these triggers?

Well, using CICS 4.1 means that you are OutOfService and not supported by IBM. A very dangerous position to be in.

Triggering does work but it depends on the TERMINAL definitions being used. I suggest you check the relevant TERMINAL definition (or the TYPETERM) to see that EXTENDEDDS(YES) is around and that the terminal device itself supports Extended LU2 datastreams.
