Can someone tell me why Jim uses "long FAR PASCAL" as a declaration for his windows message processor, in the book "Programming RPGs with DirectX", as opposed to ... I think: LRESULT CALLBACK WINAPI Is it just a legacy programming thing and Jim showing his age?

It''s the same thing. WINAPI CALLBACKs use the PASCAL calling convention. *shrug* it doesn''t matter either way.

But... but that''s what HITLER would say!!

Yes, according to my MSDN Library PASCAL is now obsolete, and the WINAPI macro, which translates to the appropriate calling convention for the target, is used instead.

I think it was just an oversight on Jim''s part. Someone correct me if I am wrong.

What does FAR mean?

It used to mean that the pointer was a far pointer (as opposed to a near pointer). Far pointers had a longer address than near pointers on 16 bit OSes (IIRC, far pointers were 32 bits while near pointers were 16 bits). These conventions are obsolete in Win32 and the windef.h defines NEAR and FAR now evaluate to empty strings (and thus are ignored).
