Need some help. I have a Deckel 50V with millplus control V400. I am having trouble calling subs from my main program. Book states G22 N="program number". This will work if the size of the program is not too big. I tried anyway and got a 251 error "program too large". I was told that for large programs (I have 4 subs from 1M to 4.9M) that I need to use G23 N="program number". I try this I get a syntax error. Anybody got an answer? Deckel does not.
