   > ... Since MS-DOS ever since version 2.0 has memory management functions (INT   
   21h/AH=48h, INT 21h/AH=49h, and INT 21h/AH=4Ah), why did Borland feel it   
   necessary to implement their own heap manager?   
      
   Another probable reason is a bug in MS-DOS memory manager wherein requesting a   
   block bigger than the bigest available block produced an error *but* also   
   "reserved" the available memory w/out returning a pointer to it (depending on   
   he DOS version).   
      
   Note also that MS-DOS allocated memory in multiples of a paragraph (16 bytes),   
   which at that time was considered somewhat wasteful; thus the proliferation of   
   custom intra-application memory managers one could find everywhere.
