Setting data
D Number of device that will store the number of repetitions remaining
Pn Number of branch destination pointer when the end of processing repetitions.
 Functions
 Forces the end of repetition processing based on the FOR to NEXT instruction loop, and shifts to the execution of the
pointer designated by Pn.
Only the pointer within the same program file can be specified for Pn.
If a pointer in the other program file is specified for Pn, an arithmetic error is resulted.
Forced end condition
BREAK
When forced end condition
has been established
Pn
 The number of repetitions remaining at the point that the FOR to NEXT loop was brought to a forced end is stored at "D".
However, the number of times when the BREAK instruction was executed is also included in the number of repetitions
remaining.
 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.
If an end is forced when there are multiple nesting levels, execute the same number of BREAK instructions as there are
nesting levels.
