Is register 2 considered volatile for the 64 bit high half? If not, then how do you know if the macro user will preserve and restore the register?

I did give it an option to retain leading zeros but the default is to strip them using the EDMK instruction. So far, I'm using the LGR, LGF, LGH, XGR/IC, and LLGF instructions to pass the data in register 2 to the subroutine. Testing looks good. Thanks all.
