I've never used G22

Here is what I found on the net:

1) G22 = Stored stroke check function ON
(G23 = Stored stroke check function OFF)

2) Google Books

From Google Books, looks like it's a safe working zone. A lot of good free info in that book.

I couldn't find anything on the CC 120 M, but according to the manual for the CC 220 M, G22 P15 is calling subroutine 15. Might just be the same on the CC 120 M.
