BREAK(P)

Forced end of FOR to NEXT instruction loop (BREAK(P))

BREAK(P)

Function

(1) Forces an end to a FOR to NEXT instruction loop and shifts the operation to the pointer 

specified by Pn. Only a pointer within the same program file can be assigned to Pn. If a 
pointer of the other program file is used, an operation error will be returned.

(2) The remaining number of the FOR to NEXT instruction loop times is stored at 

. 

Note that the remaining number includes the operation when the BREAK instruction is 
executed.

(3) The BREAK instruction can be used only during the execution of a FOR to NEXT instruction 

loop.

(4) The BREAK instruction can be used only when there is only one level of nesting. When an 

end is forced to the multiple nesting levels, execute the same number of BREAK instructions 
for the nesting levels.

: Number of the device where the remaining number of loops will be stored (BIN 16 bits)

Pn : Number of the pointer (device name (pointer)) where the program is branched at the forced end of a loop.

If the BREAK instruction is not executed, 
program returns to the FOR instruction  
as many times as the number specified  
with the FOR instruction.
