is
displayed
when
they are specified
as numerical
variables
and
a
blank
space
appears
when
recalling
a
cleared
memory
character
variable.
If
a
memory
is loaded with
-0
and specified
as a character
variable,
an error
occurs (Error
code:
1).
Also,
if
you clear a
variable
specified
as given
in General
Form
(2)
or
(3)
and
then
attempt
to
recall
it
as a numerical
variable, an error also
occurs (Error
code:
1
).
Comments:
Vacant
program
memory
areas are
available
to be used
as
flexible
memory.
Programs
can be
written
into
the
program
memory
until
its capacity is exceeded.
Accordingly,
keep
in mind
that
if
you edit
programs
(insertion,
deletion,
correction)
this
changes
program
steps or
content,
and
this
may
affect
the
number
of
flexible
memory
space available.
For
example,
when
programs
are written
as
shown
in
illustration
(A) below,
recalling
or
writing
the
contents
of
flexible
memories
A(42) or A$(42)
results in
an error (Error:
4)
because
no
flexible
memories
exist
corresponding
to
such codes.

Also, when the arrangement
of
progras written (added)
as
shown
in
illustration
(A)
is
changed
to be
as
shown in
illustration
(B),
flexible
memories
corresponding
to A(41)
or
A$(41)
and
A(40)
or
A$(40) disappear.
Thus
if
you
try to recall
or
write
to
these
memories,
an
error
occurs
(Error:
4).
By contrast,
a string
of programs
stored as
shown
in illustration
(B) can be
shortened
as shown
in
illustration
(A) (by
editing),
the number of memories available
to be
used
as flexible
memories
increases
in
proportion
to the degree
of
the
change.
(One
flexible
memory
corresponds to
8
program steps.)
Note:
When
you
try
to
recall flexible
memory
which
is loaded
with nothing,
unexpected
displays
might
appear or
an
error
might
occur
(Error:
1
).
