CLEAR
n
When used without an argument (e.g., type CLEAR and hit
[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 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
"
Let's 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-quotes (").
NOTE:
In LEVEL II, CLOAD and CSAVE operate at a transfer rate of 500
baud. This is twice as fast as. LEVEL I's cassette transfer rate. Therefore, the
Volume setting used during CLOAD should be correspondingly lower. For
example, if you're using Radio Shack's CTR-80 Cassette Recorder, try a
setting of between 4 and 6 on the Volume control when loading programs or
data you placed on the tape. For loading pre-recorded programs, a higher
Volume level may be required. Do a little experimenting.
Entering CLOAD will turn on the cassette machine and load the first
program encountered. LEVEL II 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. See also
CSAVE.
See page 10/ 1 if you have the Expansion Interface for loading from 2
recorders.
