Radio Shack Quick Printer II Owner's Manual

Tips On
Loading Disk
basic
There are several ways, other than
those
described in
the manual,
to start
up
Disk
basic.
basic program -F.files -m: address
program is a trsdos
file
specification
for
a
Disk
basic program. After
start-up,
Disk
basic
will run the
program. This
is optional.
-f: files
tells Disk
basic the maximum
number of files that may be open
at one
time, files
is
a
number from to
15. This is
optional; if omitted, 3 is used. If Variable
length files are
needed, you
must
include the suffix
v
after
files; otherwise, files
will
be Fixed length.
-w.address
tells
Disk basic not to use
memory above the specified address.
This is optional; if
omitted,
Disk
basic
uses
all memory up to
Top.
If all options are
omitted,
Disk basic will prompt with HON
MANY FILES?
and MEMORY?
The options allow you
to
specify any or all of the following:
•
A program to
run after Disk
basic is started.
•
The
maximum number
of
data
files that may be Open at one time. The larger the number of files,
the less
area
available for storing and
executing your programs.
(Note: Each
Fixed length file
takes
up 360
bytes and
each Variable length
file
takes up
616
bytes of memory.)
•
The
highest
address to be used by
Disk basic during program execution. Omit this unless you are
going to
call
machine-language subroutines.
