Interface Files Help!

[CAMPER@AppleLink.Apple.COM (Camper, Dan)]

I'm hoping someone can help me with manually updating MCL interface files.
I've been given the task of implementing portions of AOCE into one of my
projects and I pretty much continuously run into brick walls of varying height
during the process.
 
The latest hurdle to jump involves AOCE Personal Catalogs.  Unfortunately, the
interfaces for all that (and a sizeable number of other AOCE calls) were
commented out by PInterface Translator.  Here is one such call, in the original
Pascal format:
 
FUNCTION DirCreatePersonalDirectory(paramBlock: DirParamBlockPtr): OSErr;
   INLINE $7000, $1f00, $3F3C, kDirCreatePersonalDirectory, _oceTBDispatch;
 
The unadorned MCL version looks like this:
 
#| Not in ROM - INLINE =  #x7000 #x1F00 #x3F3C #x011F #xAA5E
(deftrap _dircreatepersonaldirectory ((paramblock (:pointer :dirparamblock)))
   (:stack :signed-integer)
   (:stack-trap #x0))
|#
 
All of the values in "#x7000 #x1F00 #x3F3C #x011F #xAA5E" in the MCL portion
are correct, but PInterface Translator somehow couldn't decypher a call for it.
All the calls that did _not_ include two preceding parameters in the Pascal
INLINE statement ("$7000, $1f00" in this example) translated fine.  This
worked, for instance:
 
FUNCTION DirGetDNodeInfo(paramBlock: DirParamBlockPtr; async: BOOLEAN): OSErr;
   INLINE $3F3C, kDirGetDNodeInfo, _oceTBDispatch;
 
(deftrap _dirgetdnodeinfo ((paramblock (:pointer :dirparamblock))
                           (async :boolean))
   (:stack :signed-integer)
   (:stack-trap #xAA5E paramblock async (293 :signed-integer)))
 
I freely admit to not comprehending what the hell is going on here, and I'm
hoping that someone will point me in the right direction.  It seems that if I
can figure out how to make _dircreatepersonaldirectory actually work than I can
manually alter almost all the commented-out interface calls for AOCE; that
would be a good thing, I think.  I'll even post the interface files to the ftp
site when I'm finished.
 
Anyway:  Can someone please explain to me what needs to be defined?  Any help
is appreciated!
