ABSTRACT:
ERASE INPUT support is provided for the optimizer system disclosed in commonly-assigned co-pending application Ser. No. 827,767, now U.S. Pat. No. 4,750,137, by altering the programming of the optimizer system so that the only MDT flags turned off in the optimized outgoing data stream are those associated with protected pre-modified fields. The programming is further altered so that when an incoming data stream is received by the optimizer system, all unprotected fields in the present-state image are preprocessed prior to being updated from the incoming data stream to reflect the information available to the optimizer system as to whether the ERASE INPUT key has been pressed.
