Since
eight

required
for

care
will
be
required
to
ensure
that
there
will

sufficient

when
declaring

in

For

< Variable Expansion >
Although
26
variables
(A
to
Z)
are
provided
as
a
standard
feature
of
the
com-
puter,
additional
variables
can
be
used
by
variable
expansion.
The
variables
can
be
expanded
by
using
the
DEFM
command
and
specifying
with
the
format
“DEFM
Number
expanded
(numeric
expression)”.
Example:
To
add
20
variables
for
a
total
of
46,
operate
as
shown
below
in
the
RUN
or
WRT mode.

5-3 Variables
Number of variables can be expanded up to a maximum of 1974,
The remaining capacity of free area will decrease 8 bytes for each expanded
variable so care will be required since there may be insufficient space to create
a program if expanded excessively. The table below shows the relations between
the number of variables and the maximum capacity of the free area,
