MCL developers:

I'm trying to write a register based callback routine using defpascal.
(in this case the completion routine for #_ADBOp).  The defpascal
documentation describes a syntax for getting the registers passed in
to the routine in a single record.  What is the record type of this

The following illustrates what I want to do.  A2 will contain a
pointer to a word.  I simply want to set the value of that word.

  (defpascal callback-routine (:reg registers)
    (setf (%get-word (pref registers :regbuf.ra2)) 1))

Thanks for your help.
