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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

Using Extended Memory
Extended memory can be used to store about 60K of QBX executable code,
freeing this memory for program use.
 
To use extended memory with QBX, you must have:
 
 ■ An 80286 or later processor
 ■ One 64K segment of extended memory located above the 1 MB address
 ■ The HIMEM.SYS device driver, included with BASIC, installed, or an
   extended memory device driver that observes the Extended Memory
   Specification (XMS) version 2.0, installed
