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.
