TRS-80
MODEL
III
CLEARS
When used
without an
argument
(e.g. , type
CLEAR
and
press
(ENTER)
),
this
command
resets ail
numeric variables
to zero,
and ail string
variables
to null.
When
used with
an argument
(e.g.,
CLEAR 1
00)
, this command
performs
a second
function in
addition to the
one just
described: it makes the
specified
number
of bytes
available
for string
storage.
Example:
CLEAR 100 makes
100 bytes available
for strings.
When
you turn
on the
Computer
a CLEAR 50 is
executed
automatically.
CLOAD
'
'file
name'
'
Lets
you load
a BASIC program
stored
on cassette.
Place
recorder/player
in Play
mode
(be
sure the proper
connections
are made
and cassette
tape has
been re-wound
to
proper position).
The
file name
may be any
single character
except
the
double-quote
(").
Note:
See "Using
the
Cassette Interface"
in the
Operation
Section
for instructions
on which
baud
rate to
use
.
Entering
CLOAD will
turn
on the cassette
machine
and load
the first
program
encountered.
BASIC also
lets you
specify
a desired "file'
'
in your
CLOAD
command.
For example,
CLOAD "A" will
cause the
Computer to
ignore
programs
on the
cassette
until
it comes to
one labeled
"
A" . So no
matter where
file
"A" is
located
on the
tape,
you can start
at the beginning
of
the tape; file
"A" will
be
picked
out
of all the
files on
the tape and
loaded. As
the Computer
is
searching
for
file
"
A"
,
the names
of the
files encountered
will
appear in
the upper
right corner
of
the
Display
,
along
with
a blinking
"
*
"
.
Only the
first character
of
the file name
is used
by the
Computer
for CLOAD,
CLOAD?,
and
CSAVE
operations.
Loading
a
program
from
tape
automatically
clears
out the previously
stored
program.

CSAVE.
