Example:
To increase variable I in increments of 2 between 1 and 10.
FOR I -1 TO 10 STEP 2
NEXT I
To reduce variable A in increments of 0.5 between 50 and 1.
FOR A=50 TO 1 STEP-0.5
I
NEXT A
To increase variable P in increments of 1 between Q and R.
FOR P =0 TO R
NEXT P
* When increase is performed in increments of 1, "STEP" may be omitted.
* Nesting
Up to 4 FOR-NEXT loops can be stacked. This stacking is called "nesting".
-FOR A =
-FOR B--
-FOR C=-
rFOR
i-NEXT D
I N E X T 0
NEXT B
NEXT A
This shows 4-stack nesting.
When nesting is performed in this manner, attention must be paid to the NEXT
statement and its variable which correspond to the FOR statement.
