Memory Subsystem


 The routines  provided in the Memory Subsystem were originally designed for
 the IBM-PC/MS-DOS  environment. Although  Extended and Expanded memory have
 no analog  in other  environments, these  routines will be available on all
 systems to provide full compatibility.  Under Non-MS-DOS implementations of
 TCXL, all the Memory Subsystem allocation routines will fail.

 The function  descriptions and  prototype information  for the expanded and
 extended memory functions are described in the Appendix G.
