DFHEXI executable module

Entry points

DFHEXINA

Called by

DFHZARQ

Description

The exceptional input program is invoked from DFHZCP when unexpected input is received from a z/OS Communications Server 3270 terminal that has a task attached. DFHEXI checks whether the input is the result of a 3270 print function key being pressed; if so, DFHEXI issues a DFHTC TYPE=PRINT macro, and then unlocks the keyboard; in any case, DFHEXI then passes control back to DFHZCP.
