Operation without an Operand
EXIT(806) can be executed without an operand. If it is, then an execution con-
dition must be created for it starting with LD. If the execution condition is OFF,
the rest of the block program will be executed normally. If the execution condi-
tion is ON, the rest of the instructions in the block program through
BEND(801) will not be executed.

Operation with an Operand
If the operand bit, B, is OFF for EXIT(806) the rest of the block program will be
executed normally. If the operand bit is ON for EXIT(806), the rest of the
instructions in the block program through BEND(801) will not be executed. For
EXIT NOT(806), the rest of the block program will be executed for if the oper-
and bit is ON and skipped if the operand bit is OFF.

Error Flag ER
An error will occur and the Error Flag will turn ON if EXIT(806) or EXIT
NOT(806) is not in a block program.
When CIO 0.00 is OFF, the block program is executed. If CIO 0.01 is ON, A is
executed and then B is skipped and program control jumps to BEND(801).
Section B of the program will continue to be skipped until CIO 0.01 turns OFF
again.
