The following channel-specific machine data are used to set whether the activated ASUP will
be processed without interruption although single-block processing is set or whether single-
block processing will be activated:
MD20106 $MC_PROG_EVENT_IGN_SINGLEBLOCK, bit 4 = <value>
<value> Meaning
Behavior when the read-in disable is set
The channel-specific machine data is used to set whether the ASUP will be processed without
interruption although read-in disable (DB21, ... DBX6.1 = 1) is set, or whether the read-in
disable will be effective:
MD20107 $MC_PROG_EVENT_IGN_INHIBIT, Bit 4 = <value>

The event by which the ASUP has been started is stored in the system variable
$P_PROG_EVENT. On automatic activation after a block search, $P_PROG_EVENT returns
the value "5."
