This is what I've discovered about using 'new' in small memory model with
Borland C++.

//#define FOO_NEW  (far  FOO)       //  5   |       | far  |  Compile Error

#include <stdio.h>

class FOO_DEF
   {
   char cFoo [10000];
   };  /* end-class FOO */

int main ()
   {
   FOO far * alpFoo [10];

   for (int i = 0; i < 10; i++)
      {
      alpFoo[i] = new FOO_NEW;

      printf ("Array %i is %Fp\n", i, alpFoo[i]);
      }
   return (0);
   }


/****************************/

Results: If you declare a class as 'far', you can alloc it 'near' or 'far'
         as you want.
         If you declare it 'near' you must alloc it 'near'.

Note: Don't use parentesis with the 'new' operator: Compiler error.
