You can access the 64-bit XPLINK form of the inbound parameter list for the AMODE 64 assembler routine in the calling routine's save area any time after routine initialization. CELQPRLG will always save general registers 1 through 3 in the first 3 words of the "argument area" in the caller's save area so that the parameter list is complete.

Requirement: All parameters that are passed to and from AMODE 64 assembler code be passed by reference.
