CHAPTER 6 SHORTCUTS
The
PC·3
includes several
features
which
make
programming
more
convenient
by reducing
the
number
of
keystrokes
required
to
enter
repetitive
material.
One such
feature
is
the
availability
of
abbreviations
for
verbs and
commands
(See
Chapter
8).
This
chapter
discusses
two
additional
features
which can
eliminate
unnecessary
typing
-
the
DEF key
and
the
ReSerVe
mode.
The
DEF
Key
and
Labelled Programs
Often
you
will
want
to
store
several
different
programs
in
the
PC·3's
memory
at
one
time.
(Remember
that
each
must
have
unique
line
numbers.)
Normally,
to
start
a
program
with
a RUN
or
GOTO
command,
you
need
to
remember
the
beginning line
number
of
each
program
(see
Chapter
8).
But,
there
is
an easier way! You can label each program
with
a
letter
and
execute
the
program
using
only
two
keystrokes.
This
is
how
to
label a
program
and
execute
it using
DEF:
*
Put
a label
on
the
first line
of
each
program
that
you
want
to
reference. The label consists
of
a single
character
in
quotes,
followed
by
a
colon.
10:
"A":
PRINT
"FIRST"
20: END
80:
"B":
PRINT "SECOND"
90:
END
Anyone
of
the
following
characters
can be used: A, S,
D,
F, G, H, J,
K,
L,
=, Z, X, C, V,
B,
N,
M,
and
SPC. Notice
that
these
are
the
keys
in
the
last
two
rows
of
the
alphabetic
portion
of
the
keyboard.
This area has
been
darkened
on
your
keyboard
to
make
it easier
for
you
to
remember.
