Gentlemen,
I seen in a Fanuc book that looked like two ways to program a GOTO Statement:

GOTO2
GOTO#20

The way it reads both should go to N2
I tried this on a Mazak VMC with a M-Plus control and only GOTO2 works and not GOTO#20. Does this only work on Fanuc controls?
I haven't had a chance to get on one and see, so I thought I would ask my CNC Brothers.

Thank You

what is the series of fanuc control you are using ?

18i and 31i

#20 should be looking for the Variable 20. I think this would be a local variable to the program or sub in which it is being run. If I remember right this is one that is set to null when reset is hit. Try setting the variable in your program. Like #20=50 . Then the goto#20 would be goto50.

the Mazak macro is slightly different to standard Fanuc macro and has less functionality in some cases.
either way you would only use #20 (or #number) if your program is doing calculations and putting numbers into variables and your program is doing the thinking about which line it should jump to based on those variables (this would require a lot of smart programming techniques).
otherwise if you know you want to do a jump to a specific line just put GOTO 20
