Although there have been a number of postings about dos-extenders 
recently, I still have a couple of questions. 

- ISN'T THERE A FAQ ABOUT THIS TOPIC SOMEWHERE ON THE NET ????

- The Phar Lap dos extender seems to come in two varieties:
  16 bit and 32 bit. can both types be used with the Borland C++ 3.1
  compiler ? 
  And with Microsoft C (6.0) ?

- What other good (commercial) dos extenders exist ? 

- What kind of porting problems can one expect when switching to a 
  dos extender ?

An answer to any of the above questions will be very much appreciated.

   Thanks for your time.

To use the 32-bit one you need a 32-bit compiler, like Watcom C/386 
Metaware High C, or Zortech from Symantec.

FlashTek, Inc. supplies (a crippled version) the one shipped with the 
Zortech compiler.  It is also available for Watcom.  The complete version
supports virtual memory, TSR, memory mapped files, VCPI, DPMI, and 
bare bones DOS, and is very small (< 20K) and very fast.

See my article in Dr. Dobbs, January 1993.

Contact FlashTek for a free demo disk of our DOS extender.
