routines listed, the interpreter will continue with the next executable statement.

"SubLabel" is the line label of a subroutine.

To branch to one of several specified Line Labels depending on the value of an

expression.

Syntax

ON N GOTO LineLabel {, LineLabel}

Remarks

"N" is a numeric expression which is rounded to an integer. The value of N

determines which line label in the list will be used for branching. If the value N is 0,

or greater than the number of line labels listed, the interpreter will continue with the

next executable statement.

"LineLabel" is the string label of a program line.
