• Program Storing
and
Loading
Sometimes the program cannot
be
stored because
of
the capacity
of
free area.
If
the
previous program
is
erased,
it
cannot
be
used again.
In
cases
of
this nature,
the cassette interface
is
very helpful.
Commands for storing programs
on
a cassette tape are
"SA
VE"
or
"SA
VE
ALL".
"SAVE"
can only store a program located in a single program area, while
"SA
VE
ALL"
can simultaneously store programs located in all program areas.

SA VE
ALL
Command
[ The program located in this program area
can be stored.
Programs located in all program areas can
be
stored.
The
SA VE and SA VE ALL commands are manually executed.
Example:
SAVE~
SAVE
"CASIO"
~
SAVE
ALL
~
SAVE
ALL
"FX''
~
Characters enclosed with the quotation marks
(")
after SAVE and SAVE ALL
are file names which are placed with stored programs. These programs can be
loaded later
by
specifying these names. Up to 8 characters can be used for a
file name.
LOAD and LOAD ALL commands are used to load programs from a cassette
tape
to
the
computer. The proper use
of
these commands depends
on
whether
programs were stored
by
SA VE
or
SA VE ALL.
