Radio Shack TRS-80 Trsdos & Disk Basic Reference Manual page 5

To Our
Customers
This
is
a reference
manual,
and
its
organization
reflects
the relationship
between
TRSDOS
and
DISK
BASIC.
TRSDOS
is
the
fundamental
software,
so
it's
described
first.
DISK BASIC
is
a language supported by
TRSDOS,
so
it's
described
after
TRSDOS.
(If
other languages are supported
later, they'll
plug
right in to
this
manual
along
with
DISK
BASIC.)
But
don't think
you
have
to
read
the
manual
in strict
sequence.
If
you're
an
old
hand
at
LEVEL
II
BASIC
and you
want
to start
out
with
DISK
BASIC, go ahead and
skip
to
Section
7.
You
can
refer
back
to
the
TRSDOS
sections
later
on when
you're ready or
when you
need
them.
We
hope you
enjoy exploring
this
powerful
new
computer
system!
