Hello guys,
I really wonder if anyone could explain to me the barfeeder subprogram code, I would be really grateful:

these are generally where to find these
you don't mention the model or age of the controller

#1000 / #1001 and #1002 are system variable you may not be able to see them directly but you can see the numbers in them by writing a macro statement #1=#1000
#100's is a macro variable seen in the offset pages under macro
#500's is a macro variable seen in the offset pages under macro

By the question;s of (where I can find this in my controller Fanuc?)
you would be wise to purchase a book on macro programming
Sinha- custom macro b
peter smid -fanuc cnc custom macro's

these will cover if statements /while do statements/ local variable/ global variables

these will start you on understanding what is in your bar feed program
