16. POSITIONING MODE
(g) Step repeat instruction (FOR...NEXT)
POINT
You cannot insert "FOR...NEXT" commands between a "FOR" command and a
"NEXT" command.
The steps between the "FOR (Setting value)" and the "NEXT" commands are repeated for the set
number of times. Setting "0" repeats the operation endlessly.
For how to stop the program in this status, refer to section 5.2.4 (4).
