# On...GoSub Statement; On...GoTo Statement

Branches to one of several specified lines in the program code, depending on the value of a numeric expression.

### Syntax:

    On expression GoSub Label1[, Label2[, Label3[,...]]]
    On expression GoTo Label1[, Label2[, Label3[,...]]]

### Parameters:

expression: Any numeric expression between 0 and 255 that determines which of the lines the program branches to. If expression is 0, the statement is not executed. If expression is greater than 0, the program jumps to the label that has a position number that corresponds to the expression (1 = First label; 2 = Second label)

        Exit Sub
