   Is there (gulp!) a GO function in EMACS lisp to transfer control to
   a label (probably specified by a PROG)? I know goto's aren't usually used
   in LISP, but this just one of those times... Thanks in advance...

Not that I know of.  Why on earth do you need a goto?  Try looking at
the documentation for the functions "unwind-protect" and
"condition-case".  They allow you to transfer control up through
several stack frames without having to return from each one.  They are
typically used for signal handling, but by invention of your own
signals you could probably simulate a goto fairly well.
