The current block display can be suppressed in cycles/subprograms using

DISPLOF
be displayed on single-block stops within the cycle/subprogram.
If the single block stop in the system or user ASUB is suppressed using the settings in
machine data MD10702 $MN_IGNORE_SINGLEBLOCK_MASK (bit0 = 1 or bit1 = 1),
then the single block stop can be re-activated by programming
If the single block stop in the user ASUB is suppressed using the setting in machine data
MD20117 $MC_IGNORE_SINGLEBLOCK_ASUP then the single block stop cannot be
reactivated by programming
When single block execution SBL2 is active (stop after each part program block) there is
no execution stop in the
MD10702 $MN_IGNORE_SINGLEBLOCK_MASK (prevent single block stop).
When single block execution SBL3 is active (stop after every part program block - also in
the cycle), the command is suppressed.
