Syntax: ON Offset GOTO Address1, Address2, ...AddressN
Go to the address specified by offset (if in range).
|Limit of Address entries||256|
The ON...GOTO instruction is useful when you want to write something like this:
IF idx = 0 THEN Case_0 ' idx = 0: jump to label "Case_0" IF idx = 1 THEN Case_1 ' idx = 1: jump to label "Case_1" IF idx = 2 THEN Case_2 ' idx = 2: jump to label "Case_2"
You can use ON...GOTO to organize this into a single statement:
ON idx GOTO Case_0, Case_1, Case_2
This works exactly the same as the previous IF…THEN example. If the value isn't in range (in this case if value is greater than 2), ON...GOSUB does nothing and the program continues with the next instruction after ON.
