If
you press
(ENTER),
several things will happen: the computer enters BASIC and then
loads and executes PROG1.BA. You will see
THIS
IS
A TEST
OF

COMPUTER
AND
ITS
ABILITY
TO
STORE
FILES
Ok
•
with the Ok prompt indicating that you are in BASIC.
If
you list the program you will
see that PROGl.BA is in working memory.
Experiment
#3
Changing a Filename
It
is
possible to change a file name using the command:
NAME
"old
filename. extension"
AS
"new
filename. extension"
where oldfilename
is
the name
of
the program
as
it now exists, and new filename
is
the.
new program name you wish
to
assign to it.
For example, if you wish to change the filename "PROG
1"
to
"TEST!,"
typc:
NAME
"PROG 1 •
BA"
AS
"TEST
1 •
BA"
(ENTER)
Verify the name change with the FILES command or
by
pressing
CEf).
Now, using the NAME
...
AS
command, change the file name back to
"PROGl."
NAME
"TEST1.BA"
AS
"PROG1.BA"
~
Again, you may confirm that the name was changed to PROGI with the FILES
command.
Experiment
#4
Saving a Program on Cassette
While
it
is convenient to save your programs in RAM, there
is
only a finite amount
of
space available. Eventually, there will
be
no
room left for new programs to be saved.
An alternate method
of
saving your files
is
to store them on cassette tapes using a
cassette recorder. Using cassettes, you can store essentially an unlimited number
of
programs.
