A simpler way to save a program in RAM,
is
to use the SAVE Function Key,
~.
After typing a program you wish to save, simply press
~.
The Computer will
prompt you with the message:
Save
"
All you have to do then
is
to type a name for the file
as
you did before and press
(illEID.
The number
of
files which can be saved is limited only by the amount
of
RAM
available.
If
you continue to add files to RAM, eventually all available RAM will be
used
up
and
no
more programs can be saved.
Experiment

Loading a Program From RAM
After you have saved a program in RAM, you may execute it simply
by
positioning
the Cursor over the word identifying it in the Main Menu and pressing
(ENTERJ.
However,
if
you wish to modify or alter the program in any way, it
is
very convenient
to LOAD
it
into the BASIC system.
Let's use PROG

BASIC system.
You can do that with the command:
LOAD
"PROG1"
~
Another way to LOAD the program
is
to
press
the
LOAD Function Key.
CE2l.
After
pressing
~
the message
Load
"
appears on the Display. All you should
do
then
is
to type
PROG
1"
(ENTER)
After Loading PROG1 with the LOAD command or (f2), LIST the program to verify
that it is indeed in working memory. The following should be displayed:
List

PRINT
"THIS
IS
A
TESTH

PRINT "OF
THE
MODEL

If you execute the program with the RUN command you will see that the output
is
the
same
as
