FOR counter = start TO finish [STEP increment]

Initiates a FOR-NEXT loop with the ‘counter’ initially set to ‘start’ and incrementing in ‘increment’ steps (default is 1) until ‘counter’ equals ‘finish’.
The ‘increment’ must be an integer but may be negative.

NEXT [counter-variable] [, counter-variable]…

NEXT comes at the end of a FOR-NEXT loop.

The ‘counter-variable’ specifies exactly which loop is being operated on.

If no ‘counter-variable’ is specified the NEXT will default to the innermost loop. It is also possible to specify multiple counter-variables as in:

NEXT x, y, z
