Further information
● Program section repetitions can be nested. Each call uses a subprogram level.
● If
M17 or RET is programmed during processing of a program section repetition, the
repetition is canceled. The program is resumed at the block following the
REPEAT line.
● In the actual program display, the program section repetition is displayed as a separate
subprogram level.
● If the level is canceled during the program section repetition, the program resumes at the
point after the program section repetition call.
Example:
Program code Comments
N5 R10=15
N10 BEGIN: R10=R10+1 ; Width
N20 Z=10-R10
N30 G1 X=R10 F200
N40 Y=R10 ; Interrupt level
N50 X=-R10
N60 Y=-R10
N70 END: Z10
N80 Z10
N90 CYCLE(10,20,30)
N100 REPEAT BEGIN END P=3
N120 Z10 ; Resume program execution.
N130 M30
● Check structures and program section repetitions can be used in combination. There
should be no overlap between the two, however. A program section repetition should
appear within a check structure branch or a check structure should appear within a
program section repetition.
● If jumps and program section repetitions are mixed, the blocks are executed purely
sequentially. For example, if a jump is performed from a program section repetition,
processing continues until the programmed end of the program section is found.
