Disk Operating
System.
An
application pro-
gram
seldom talks
to the hardware directly.
It
talks through a disk operating
system.
Your
computer's disk
operating system is
TRSDOS Version
6.2.1 (or any later version).
It
is
on the diskette
that comes with the com-
puter, and is referred
to throughout this man-
ual as either "TRSDOS"
(pronounced Triss
Doss) or
—
when further
clarification is
needed
—
as "TRSDOS
Version
6."
To accomplish
anything with your disk system,
you need TRSDOS.
For example, assume
you
want the computer
to
print
a list of your check-
ing transactions.
Your application program
de-
cides what
to print. It then leaves
the
operation
of the printer to TRSDOS.
The rest
of this manual shows
you how to
store information,
using your computer,
TRSDOS,
and a short BASIC program
that
you write.
