BLIMEMMAX        (Clipper )
------------------------------------------------------------------------------

  Function : Get largest free Clipper memory block

  Syntax   : nuValue = BLIMEMMAX ()

  Return   : Size of largest free memory block in bytes.

  This function returns the size in bytes of the largest available block
  of dynamic memory. Dynamic memory is the memory used by Clipper to store
  all temporary values of variables and buffers while an application is
  running.

  This can be used to prevent the failure of memory intensive operations
  such as MEMOEDIT() which require large blocks of contiguous memory for
  successful operation.

  Example  :
  *  Get the size of the largest available block
  *
  ? "The largest available block of memory is"
  ?? BLIMEMMAX(), " bytes"
