Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

▀ The memory allocation strategies are:
  First Fit: MS-DOS searches the available memory blocks from low addresses
  to high addresses, assigning the first one large enough to satisfy the
  block allocation request.
  Best Fit: MS-DOS searches all available memory blocks and assigns the
  smallest available block that will satisfy the request, regardless of its
  position.
  Last Fit: MS-DOS searches the available memory blocks from high addresses
  to low addresses, assigning the highest one large enough to satisfy the
  block allocation request.
 
▀ The default MS-DOS memory allocation strategy is First Fit (code 0).
