DFHMCP

Description

The non-3270 input mapping program performs all BMS input mapping functions for all devices except the 3270. On exit from the module, the input data has been mapped into a newly acquired TIOA that is returned to the application program and is then addressable using BMS DSECTs in the application.

The main subsections of DFHIIP are:

IIMID  - GETMAINs TIOA to return to user, and maps
         page buffer into it using specified map.
IIREAD - Reads input data, issuing DFHTC or DFHDI
         requests to get data from the terminal.
IISCAN - Scans data stream for device-dependent
         control characters and creates page
         buffer.
