argument can be either positive or negative. The value of the step
argument specifies loop processing as follows:
step >= 0: loop executes if counter <= end.
step < 0: loop executes if counter >= end.
If the loop starts then all statements in the loop have executed, and 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

statements may be placed anywhere in the loop. Exit For
is often used with the evaluation of some condition (e.g. If...Then...Else
), and transfers control to the statement immediately following Next
