                                 GEMDOS


GEMDOS contains functions which comprise the highest level of TOS. In many
cases, GEMDOS devolves into BIOS calls which handle lower level device
access. GEMDOS is responsible for file, device, process, and high-level
input/output management. The current revision number of GEMDOS is obtained
by calling Sversion(). You should note that the GEMDOS versio number is
independent of the TOS version number and you should not count on any
particular version of GEMDOS being present based on the TOS version present.

Much of GEMDOS closely resembles its CPM 68k and MS-DOS heritage. In fact,
the file system and function calls are mostly compatible with MS-DOS. MS-DOS
format floppy disks are readable by an Atari computer and vice-versa.

For the creation of MultiTOS, GEMDOS was merged with the MiNT operating
environment which derives many of its calls from the UNIX operating system.
