The non-3270 input mapping program (DFHIIP) is called in response to requests for BMS
services involving terminals other than IBM® 3270 Information
Display Systems.
Figure 1 shows the relationships between the components of non-3270
input mapping. Figure 1. Non-3270 input mapping
interfaces
A RECEIVE MAP request by an application program, communicating with other
than an IBM 3270 Information Display System, passes
information through the TCA through the mapping control program (DFHMCP) to DFHIIP.
The map required for an operation is either passed by the application program or loaded by
DFHMCP.
DFHIIP communicates with storage control to obtain and release buffers for mapping
operations.
