TRS-80 MODEL III
CLEARn
When used without an argument
(e.g.,
type CLEAR and press
(ENTER)),
this
command resets all numeric variables to zero, and all string variables to null. When
used with an argument
(e.g.,
CLEAR 100), this command performs a second
function in addition to the onejustdescribed: 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
Computera
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 groperconnections are made and cassette tape has been re-wound
to properposition). The file name may be any single characterexcept 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. Forexample, CLOAD
"A"
will cause the Computerto 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 onthe tape and loaded. As the Computer
is
searching for
file"
A"
, the names
of
the files encountered will appearin the upperright corner
of
the Display, along with a
blinking'
'*'
,.
Only the first character
of
the file name is used by the Computerfor CLOAD,
CLOAD?,
and CSAVE operations.
Loading a program from tape automatically clears out the previously stored
program. See also
CSAVE.
