Can you combine Borland C/C++ or Turbo C/C++ code with your
 CA-Clipper applications?

 Yes, if you follow these guidelines:

 1. Use large model only (the -ml command-line compiler switch).
 2. Use no floating point operations, and disable them with
     the -f- switch.
 3. Use no Borland library functions; you may use standard C
     functions if they are found in CLIPPER.LIB or LLIBCE.LIB.
 4. You may leave register variables on and/or optimize
     for registers/jumps/speed.
 5. You may use the -v switch to include debugging information
     in your object code for Turbo Debugger.
 6. Turn stack checking off.
 7. If you use inline assembly, push DS before doing anything
     and pop it when done, unless you are SURE your code doesn't
     do anything to affect DS.

 One workable set of switches seems to be:

                             -c -f- -ml -N-

 These switches work, delivering optimized C code:

                       -c -f- -ml -N- -Z -O -G -w
