BREAK
BREAK
The BREAK instruction is used to cancel repeat processing from the lowest level FOR instruction to the
NEXT instruction.
None
The BREAK (EXIT) instruction cancels the repeat processing from the lowest level FOR instruction to
the NEXT instruction (the END_FOR instruction for ST). It moves processing to the next instruction
after the NEXT instruction. The processing between the BREAK instruction and the NEXT instruction
(or the EXIT instruction in ST) will not be executed.
The following figure shows a programming example. When the FOR loop is executed, the value of vari-
able A is checked each time. If the value of variable A is TRUE, the repeat processing is ended immedi-
ately. In this example, the Out instruction after the BREAK instruction is not executed, and the value of
variable C is retained. (In ST, the EXIT instruction is used instead of the BREAK instruction.)
