This is an omission in MCL's documentation. Here's the missing text:


FINDER-PARAMETERS                        [function]
returns a list whose CAR is either :OPEN or :PRINT and whose
CDR is a list of pathnames. This list represents files that
were passed to MCL by the Finder when MCL was launched. Under
System 7, this information is passed by the initial 'odoc' or 'pdoc'
AppleEvent, which MCL conveniently processes for you. The BINHEX-STARTUP
function in the file "ccl:examples;binhex;binhex.lisp" is an example
of using FINDER-PARAMETERS.
