   In the post that I made which asked about running BCX within Windows
(again I apologize for wasting bandwidth on a question that I should have
solved myself by reading the manual), I listed compile-and-link times for
two simple Windows programs.  The difference that I saw was VERY NOTICEABLE.
In case you missed my earlier post, here are the numbers again:


PARTY.C    (from Petzold's "Programming Windows" book):
        BC  --  5.5 minutes.
        BCX --  16 seconds.
WHELLO.CPP (from Borland's sample programs)
        BC  --  8 minutes   (that's right EIGHT MINUTES!)
        BCX --  40 seconds.


   Of course my machine isn't nearly as monstrous as yours so you may not
get the same type of results as I did.  My hardware is much more modest:
        * * IBM PS/2 Model 55sx   with  4 Mbytes of memory. * *
