you
want
the
PC-3
to
treat
a
number
as
hexadecimal,
put
an
ampersand
(&)
character
in
front
of
the
numeral:
&A
10
&10
16
&
100
256
& FFFF '"
65535
Those
with
some
computer
background
may
notice
that
the
last
number
(65535)
is
the
same
as
the
largest
number
in
the
special
group
of
limits discussed
in
the
last
paragraph.
Hexadecimal
notation
is
never required
in
using
the
PC-3,
but
there
are special
applications
where
it
is
convenient.
String Constants
In
addition
to
numbers,
there
are
many
ways
that
the
Radio
Shack
PC-3 uses
letters
and
special
symbols.
These letters,
numbers,
and
special
symbols
are
called
characters.
These
characters
are available
on
the
PC-3.
1 2 3 4 5 6 7 8 9 0
ABCDEFGHI
J K
!"#$%&()*+,
LMNOPORSTUVWXYZ
/:;<=>?@yrrAIE
In
BASIC, a
collection
of
characters
is
called a string.
In
order
for
the
PC-3
to
tell
the
difference
between
a string
and
other
parts
of
a
program,
such as verbs
or
variable
names,
you
must
enclose
the
characters
of
the
string
in
quotation
marks
(").
The
following are
examples
of
string
constants:
