Hi,
As I remember it belong to a mismatch between map and data area's defined in your program and one or both of them could be in error!
Usually the data would be showed in the screen up to the field which has wrong attribute(numeric/alphanumeric) or wrong positon.
Check the definition of the map and the area which you defined for map copy book in your program and if there is not any error recompile them maybe it repairs the error!
Above is a hint and I wish it helps you.

Hi Kamran,

Thanks for ur suggestion.

the data was having a junk value x'15' and it was causing the problem.

i edited that data and this time no error came.

is it possible to check if any non-displayable character comes that should be changed to spaces or any other displayable character

Hi nankrish,

It is not a good idea to change any none displayable data to displayable character because some of them are attribute, position or other valid fields of the 3270 data stream.It is better to check the input with any valid charachter range including alphanumeric and special charachters and also valid 3270 data stream fields like cursor position, function codes and fields attribute and position.

Hi kamran,

Is there anywhere I can fing a list of valid 3270 data stream fields/characters?

Because in our installation we are trying to simulate this type of abend and I need to know what type of data will cause this type of abend.

Hi,

Unfortunately I don't have any complete and reliable self explanatory document about 3270 data stream but you can find a useful short tutorial which is covered just 3270 data stream structure bellow:
http://www.tommysprinkle.com/mvs/P3270/
I hope it satisfies your needs
regards
