7.6 Structure Creation Instructions
Forced end of FOR to NEXT instruction loop
BREAK(P)
• 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.
• The remaining number of the FOR to NEXT instruction loop times is stored at (D). Note that the remaining number includes
the operation when the BREAK instruction is executed.
• The BREAK instruction can be used only during the execution of a FOR to NEXT instruction loop.
• 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.
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
(D): 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.
