FOR numeric-variable = numeric-expression TO numeric-expression
NEXT
 
FOR numeric-variable = numeric-expression TO numeric-expression STEP numeric-expression
NEXT

Creates a counting loop. In the first form, the loop variable increases by 1 each time control reaches NEXT.
In the second form, the loop variable changes by the STEP amount each time.

If STEP evaluates to a negative value, the variable will decrement towards the lower value.

Loops may be nested. NEXT closes the nearest unmatched FOR.
