Updated Forth OO Extensions Files

The Neon ANS compatible extensions have been updated and are available
as .zip archives at the following URL:

File class20f.zip is for PC users
File class20mf.zip is for Macintosh (MacForth) users

The important changes to this version are to the method compiler:

1) Inside a class definition one can now obtain the address of an ivar
simply by executing its name.

2) Inside a class definition we can now use a never-before-defined
selector in a late bind. The method compiler will automatically handle
this correctly.


These files have been tested on the following Forths and OS's:

Carbon MacForth on OS X 10.3.9 iMac G3

Gforth v 0.6.2 on Windows XP Dell Dimension Pentium 4

SwiftForth v 2.2.2.9 on Windows XP Dell Dimension Pentium 4

VFX Forth VFX Forth for Win32 v 4.10 on Windows XP Dell Dimension Pentium 4


In addition to the original library classes provided by Andrew McKewan,
you will find several new classes and their descriptions.

Files for both linked-list and dispatch table based late-binding are
included. Take your pick. The linked-list is simpler in
implementation. The dispatch table is very fast. Usage is identical.
