Moving steadyrest and tailstock in program.

Hi all!
I have a part that requires a tailstock and I have to clamp the looong tailstock on the steadyrest as I cannot get it out of the way.. I can move the steadyrest manually selecting head B and using G0Z500 for example.. I can then clamp the steadyrest using M79. However, when I put all this into the program I get all kind of errors and trouble when I need to restart from a specific N.

Does anyone have a small sample program so I can see how to do it correctly?

I'm switching between the turret (head A) and the steadyrest (head B) using G14 and G13. I have something like this to bring the steadyrest+tailstock:

N77
M78
G14 - switch to steadyrest
N77
P3
G0Z-935 - move steadyrest in position
N888
G13 - switch back from steadyrest.
M56 - bring tailstock
M79 - clamp steadyrest on tailstock

When restarting I need to select head A, restart from N77, then select head B, restart from M888. Kind of works but it's not working when running from the beginning.. It's like both heads run in the same time (and of course that's not possible, they need to follow a certain sequence..). There should be some P's in there.. Not sure what they mean? Priorities? How do you sync something like this?

Thanks!
