As
you
complete
the
entry
of
each line (by pressing
the
ENTER keyl,
notice
that
SHARP
expands any abbreviations
on
that
line.
The
resulting clarity is immensely valuable
to
your
l
ate
r,
as you check
the
program for errors.
An
additional hidden benefit
is
that
the
space used
to
store
the
abbreviations for the statements
is
no
more
(or less)
than
the
space used
to
store
the
lull
statement. Thus,
tlhe
abbreviation facility
is
strictly a convenience for
you,
the
prog
rammer.
To enhance readability we
will not ·use these abbreviations in
our
sample program listings
(although you
may,
of
course, when
en
teri
ng
the
programs).
The
following
are
the allowable
abbreviations for
commands
and
statements alr
eady
introduced:
PR
INT
P.
PR.
PR!.
P'AUSE
PA.
PAU.
INPUT
I.
IN.
!NP.
RUN
R.
A complete list
of
abbreviations
is
included
in
the
bac
k
or
this
ma
nual as an Appendix.
