1. Object types and formats. This table
shows
the
correct delimit-
ers
and
examples for
the
10 basic types of object.
An
"object" is
any
of
the
individual
items you
work
with
on
the
calculator.
The
10 basic
object types are:
• Real
numbers,
such
as 5
or
-4.3
X 10
15
.
• Complex
numbers,
which
are
a
pair
of
real
numbers
representing
a
complex
number
x +
iy
or
a
point
in a plane.
• Binary integers,
which
are
unsigned
integers
used
in
computer
science.
• Strings,
which
contain
arbitrary
sequences
of characters.
• Vectors,
which
are
one-dimensional
arrays
used
in
linear
algebra.
• Matrices,
which
are
two-dimensional
arrays
used
in
linear
algebra.
• Lists,
which
contain
arbitrary
sequences
of
objects.
•
Names,
which
enable
you to
name
and
store
other
objects
and
to
perform
symbolic calculations.
• Programs,
which
enable
you to create
your
own
commands.
• Algebraics,
which
represent
mathematical
expressions
and
equations.
2. Menu selection (shifted). Use
the
menu
selection keys to assign
commands
to
the
menu
keys. For example, press
.1
ARRAY I to select
the
ARRAY
menu.
To
select a
different
menu,
press
another
menu
selection key.
There are
additional
menu
selection keys
on
the
right-hand
keyboard
(see
item
16).
3. Object delimiters.
These
symbols
identify
the
different
object
types (see
item
1). For example, 0 identifies
binary
integers,
while
0
and
.0
identify
programs.
Real
numbers
require
no
delimiters. Symbolic objects
(names
and
algebraics) require
the
CJ
delimiter, located
on
the
right-hand
key-
board
(see
item
11).
4. Lowercase. Press
o:;QJ
to
key
in lowercase letters. Lowercase
mode
continues
until
you press
o:;QJ
a
second
time, press 1 ENTER I to
process
the
command
line,
or
press
ION
I to clear
the
command
line.
