Called by

DFHBMS macro, DFHEMS

Description

The mapping control program processes DFHBMS macro requests and completes the processing of a logical message when a task terminates without issuing a DFHBMS TYPE=PAGEOUT. DFHMCP’s main function is to analyze DFHBMS requests and to pass control to the appropriate modules. Other functions include the loading of maps and partition sets, and scheduling of output messages transmitted by temporary storage.

The main subsections of DFHMCP are:

MCPCPO   - Completes logical message build message
           control record for temporary storage
MCPDWEXT - DWE processing, invoked by DFHKCP to
           complete BMS processing at application
           termination
MCPINPT  - Handles all input requests
MCPIN    - TYPE=IN (EXEC CICS RECEIVE MAP)
MCPMAPLO - Loads map set and locates map
MCPPGBLD - TYPE=PAGEBLD|TEXTBLD (EXEC SEND TEXT)
MCPPGOUT - TYPE=PAGEOUT (EXEC CICS SEND PAGE)
MCPPURGE - TYPE=PURGE (EXEC CICS PURGE MESSAGE)
MCPROUTE - TYPE=ROUTE (EXEC CICS ROUTE).
