ON expression% GOSUB line-list

ON expression% GOTO line-list

expression%	An expression in the range 0 through 255.
line-list	A set of labels or line numbers. If the value of the expression is 1, the program branches to the first line in the list; if the expression is 2, it branches to the second line, and so on.
SELECT CASE provides a better way to perform multiple branching.


FOR i% = 1 TO 2
		ON i% GOSUB One, Two
NEXT i%
END

One: PRINT "One"
RETURN
Two: PRINT "Two"
RETURN
