If the operand bit is OFF (ON for WAIT NOT(805)), the rest of the
instructions in the block program will be skipped. In the next cycle,
none of the block program will be executed except for the execu-
tion condition for WAIT(805) or WAIT(805) NOT. When the execu-
tion condition goes ON (OFF for WAIT(805) NOT), the instruction
from WAIT(805) or WAIT(805) NOT to the end of the program will
be executed.
