Subject: CP/M documentation query

The complaint was raised at a CP/M presentation at the Computer
Faire that no CP/M documentation lists register and stack usage
by BIOS call.  (I.e. what registers are preserved and how much
stack gets used).

Does anybody know of any documentation listing the above?  If so,
is it machine readable?  Reply to Info-Micro@AI.  Thanks.
