Examples
Example 1: Repeat individual program line
Program code
N10 POSITION1: X10 Y20
N20 POSITION2: CYCLE(0,,9,8)
N30 ...
N40 REPEATB POSITION1 P=5
N50 REPEATB POSITION2
N60 ...
N70 M30
Example 2: Repeat program section between jump marker and REPEAT statement:
Program code
N5 R10=15
N10 Begin: R10=R10+1
N20 Z=10-R10
N30 G1 X=R10 F200
N40 Y=R10
N50 X=-R10
N60 Y=-R10
N70 Z=10+R10
N80 REPEAT BEGIN P=4
N90 Z10
N100 M30
Example 3: Repeat section between two jump markers
Program code
N5 R10=15
N10 Begin: R10=R10+1
N20 Z=10-R10
N30 G1 X=R10 F200
N40 Y=R10
N50 X=-R10

Number of program section repetitions
Type: INT
The program section to be repeated is repeated <n> times. After the last
repetition, the program is resumed at the line following the REPEAT/REPEATB
line.
Note:
In the absence of a number being specified for P=<n>, the program section is
repeated just once.
