Hi All,

I am running into an issue with display a screen in IMS. As far as I can tell the underlying code runs successfully with no errors but when the screen gets launched I get XPROG 751 error. This is using 24x80 and 43x80 so I am getting the same error on both devices.

I read about the XPROG 751 error and it states that it occurs when the code is trying to send DBCS data (which I am not). I even had all the message values initialized (except for the transaction code of course) just before the ISRT call but still no luck.

Any help on this is greatly appreciated.

Thank You.

This is a DATA ERROR. It has nothing to do with the application. It has nothing to do with the screen size.

One or more of the bytes you are sending to the screen are not valid in the context they are used in. It could be the actual data values you are sending, or it could be how the map is defined. But something you are sending is not correct.
