The "obvious" way is to look at the length returned from TGET 
and use that to stop the scan. No need to waste cycles on 
clearing storage or reading unchanged fields.

One thing not mentioned - depending on the model of 3270, or 
your emulator, when the user erases a field, the MDT may get 
set, and the input stream won't have any text (just the 11 field 
start). You'll need to decide whether to reinstate the previous 
text or treat it as cleared.
