How do I discover if a mandatory field (attrb=fset) of a screen was changed by the user?

(I know how to do it with a non-mandatory field.)

Greetings from Sao Paulo - Brazil

nightrider,

Check the MDT which is a Bit in the attribute byte indicating modification of field on screen.If the user keys in any data into the field, it turns the MDT ON indicating that the data is modified.

Hope this helps...

Cheers

I never treat attribute byte at bit level. May you explain a little better?

In every case, thank you in advance

Just in time:

We need to remember that user can press "erase eof" or "erase input" key. And, if I use attrb=fset, the field was ever send back from the screen to program when a receive is executed...

This is the reasons of my doubt about your answer.
