DFHIIP (non-3270 input mapping)

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.

  1. 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.
  2. The map required for an operation is either passed by the application program or loaded by DFHMCP.
  3. DFHIIP communicates with storage control to obtain and release buffers for mapping operations.
