Hello,

Even with the correction, it is not clear what you are asking or saying.

Do you have some doubt about the 3270-emulator program that is running on your desktop or is your question about some mainframe component?

Dear Dick,

the MDT gets set by the hardware (or PC emulator) whenever a field us updated. This is part of the 3270 specification, and nothing to do with CICS. It's been that way for almost 40 years.

MDT set to 0 when user is not entered any data
MDT set to 1 when user entered data

The length data value fieldL shows that data has been entered in the field (i.e. modified) if it is > 0.

So i suggest him to validate fieldL or FieldI for his requirement.

Suggestion are welcomed, see we are all here for learning icon_wink.gif

move an NOFSET (MDT OFF) attribute to FIELDA


you need this to set the field (or fields) to a NOT modifief state (MDT OFF)
before sending map to the screen.

This will provide the capability to check the true length of the number
of characters entered for a particular field.

Standard BMS stuff.
