FOR NEXT

Action

Repeats a group of statements a specified number of times.

Syntax

FOR $counter = start TO end [STEP step]

statements…

NEXT

FOR NEXT loops can be nested as many times as memory allows.

Parameters

Counter

Numeric variable used as a loop counter.

Start

Initial value of $counter.

End

Final value of $counter.

Step

Amount counter is changed each time through the loop. If not specified, step defaults to one. The step argument can be either positive or negative. The value of the step argument determines loop processing as follows:

Value Loop executes if

Positive or 0 $counter <= end

Negative $counter >= end

Remarks

Once the loop starts and all statements in the loop have executed, Step is added to counter. At this point, either the statements in the loop execute again (based on the same test that caused the loop to execute initially), or the loop is exited and execution continues with the statement following the Next statement.

Changing the value of counter while inside a loop can make it more difficult to read and debug your code.

Example

For $Count = 0 To 10 Step 2

? $Count

Next
