Note
The contents of the system variables $P_S, $P_DIR and $P_SGEAR may be lost after block
search due to synchronization operations.

Example
Block search for contour with suppression of output of the spindle-specific auxiliary functions and start of an
ASUB after output of action blocks.
Parameter assignment: MD11450 $MN_SEARCH_RUN_MODE, bit 2 = 1
After the block search on N55, the ASUB is started.
