GOTO statements have the same format as a FANUC machine (and many others). However, if you're dripfeeding, you can't GOTO beyond what remains in the front memory or main memory buffer. Many controls will simply give you an alarm. There are some ways around this by using WHILE/DO loops or sub-programming for example. But drip feeding puts a lot of limitations to what you can or can't do for many controls...
What control model are you using? Some of this you can get around by using the memory card or USB instead of RS-232....
It's just a part..... cutter still goes round and round....
