None

The optional "NONE line-ref" parameter allows you to specify the line that control should go to when the value of the numeric expression does not fall into the indicated range. This branch is treated as a GOSUB branch rather than an error-processing branch. The branched-to subroutine must end with a RETURN statement.

Used with the following statements:

• On Gosub
• On Goto
