GOTO comand, Mazak

Hey guys,
Wondering if I can get a refresher on the format for using the GOTO command of jumping to a certain line in the program on Mazak.
This is what I have that is not working...
GOTON135
M98P1491
M00
M98P1492

N135 M30

Ive tried different locations for the N135, different numbers.. all that, but no dice.

Error is as follows...

843 Designated SNo. Not found

Im having trouble understand what the book wants me to do with the "setting the correct sequence number in the appropriate block"

any help would be nice,
Thanks

I think you want to leave out the N just use GOTO135

Yes... what Chucker said....

The 'N' doesn't belong in the GOTO statement. Take it out....

GOTO will automatically scan for the "N" number you designate. So, GOTO135 will look for N135
