2.5.3 Automatic start of an ASUB after block search
Activation
The automatic ASUB start after block search is configured in the existing machine data:
MD11450 $MN_SEARCH_RUN_MODE
with bit 1 = 1 (TRUE).
Bit 1 = 1: Automatic start of user program
/_N_CMA_DIR/_N_PROG_EVENT_SPF as an ASUB.
When the last action block is activated, user program
/_N_CMA_DIR/_N_PROG_EVENT_SPF is started as an ASUB.
Start event
The event that has started this user program can be determined by scanning system variable
$P_PROG_EVENT. If it is an ASUB Start after a block search, the value 5 can be scanned
using system variable $P_PROG_EVENT.
Note
For further information about the parameter assignment for specific events, see "Event-
driven program calls".
