PMODE pages
An excellent protected mode programming resource, slightly focussed
on but not limited to Watcom.
The Delphi- WDOSX Project
Extremely comprehensive programming framework and tons of information.
If you're into using Delphi with WDOSX and still haven't been there, you're
definitely missing out on something! Since the last WDOSX release, I've
fixed two issues the Win32 emulation had with the handling of resources.
Immo, the DWP maintainer, ran into these while working on his project.
You can download the fixed kernel32.wdl from here.
Just put in place of the one that came with WDOSX 0.96.
P32 Pascal Compiler
A freeware 32 bit Pascal compiler
Pascal Pro Compiler
Another free 32 bit Pascal compiler + source. Supports WDOSX true flat
model.
Sudley Place Software
If Wudebug isn't enough for your debugging needs, you may want to try
their free 386SWAT debugger. Looks like there's virtually nothing that
thing doesn't debug...
ALINK
A free linker that links OMF/LIB to COM, MZ and PE. Specifically the
author mentions its use with NASM.
DPMI
0.9 specification
You may need this one to make full use of WDosX's capabilities
Check the
pmode directory on X2FTP for other freeware extenders
...if you don't like WDosX, that is. Or check out
Cristopher Heng's Website
That not only contains links to other free DOS extenders but also to
free compilers etc.
