Calculations
using
memories
The
TRS-80
Pocket
Computer
has
two
types
of
data
memories:
fixed
memory
(26 in
ail)
and A
flexible
memory.
In
this
section
we'll
give
examples
of
calculations
using
fixed
memories
(For
details,
refer
to
page
45.)
Specifying
memories
(T)
The
fixed
memories
are
given
labels
A
through
Z
(each
being
specified
by
the
CE through
HH
keys).
'
'
Example:
When
memory
A
is
loaded
with
4 and
memory
B with
5.

manual
calculation
In
manual
calculations,
you
can
designate
and
solve
two
or
more
expressions
in
succession
by
separating
them
with
a
comma.
However,
the
