Description
(1) Control passes to one of the dine numbers> accord­
ing to the <numeric expression> value. In other words,
control passes to the line number which matches the
value of the <numeric expressions
(2) The <numeric expression> value must be within the
range of 1 through the number of dine numbers>. If it
includes the fraction part, it is automatically round­
ed; if it is negative or exceeds 255
an error occurs.
(3) When the <numeric expression> value is 0 or exceeds
the number of dine numbers>, this instruction is not
executed and control passes to the next statement.
