Hello Netland.  I was recently disassembling an XCMD.  Along the way, I ran
into
a large group of _Pack4 calls.  These are the calls for The Floating Point 
Package.  

According to Inside Macintosh, (II - 406) :  {paraphrased}

  The macros for calling the Floating-Point routines push a two-byte 
opword onto the stack and then invoke _Pack4.  These macros are fully 
documented in the Apple Numerics Manual.

  It's the last part that is the problem.  I need to figure out what each
call is.  Unfortunately that is all IM says about _Pack4.  Does anybody know 
where I can find the list of opwords?  I know of no local copies of the Apple
Numerics Manual.  Does anyone know of an FTPable list?  Any one care to type 
one in?  I don't need lengthy documentation, just a table of the Opwords and 
what they mean.
