(D)
Device used for loop control counter
(S1)
Initial value of loop control counter
(S2)
Final value of loop control counter
(S3)
Incremental value of loop control counter
(1) (S1) is substituted to the device specified with (D) as initial value, and the block
between FOR and NEXT is repeatedly executed.
(2) The incremental value specified with (S3) is added to the device specified with (D)
at every execution of NEXT. If the device value specified with (D) is larger than the
final value specified with (S2), the repeat control of the block between FOR and
NEXT is ended, and the next block of NEXT is executed.
(3) When the incremental value specified with (S3) is negative number, if the device
value specified with (D) is smaller than the final value specified with (S2), the
repeat control of the block between FOR and NEXT is ended.
(4) STEP can be omitted. If STEP is omitted, the repeat control is executed as "STEP
1".
