From

TAB
After those
last
lessons
let's
take
an easy
one.
We
already
know
3
ways
to set
up
our output
PRINT
format.
We
can:
1.
Enclose
what we want
to say in
quotes,
inserting
blank
spaces
as
necessary.
2.
Separate the objects of the
PRINT
statement with semicolons
so as
to
print
them
tight-
ly
together
on
the
same
line.
3.
Separate the objects of the
PRINT
statement with
commas
to print
them
on
the
same
line
in the four different print
"zones."
A
fourth
way
is
to use the
TAB
function,
which
is
similar to the
TAB
on
a regular type-
writer.
It is
especially useful
when
the
output
is
columns
of
numbers
with headings.
Type
in
the following
program and
RUN:
10
PRINT TAB
(
5
) ;
"
THE
"
;
TAB
(
20
)
;
"
TOTAL
"

TAB
(
35
) ;
"
SPENT
"
20
PRINT TAB(5)
;
"BUDGET"
;
TAB< 20)
;
"YEAR'S"
;
TAB
(

) ;
"THIS"

"CATEGORY "

The
RUN
should appear:

and
3.
PRINT
TAB
(
);
"
";TAB(
);"
";TAB(

to set
up
the headings given
in
the
prior
example. Use form
1 for
the
first line
of the head-
ing,
form 2
for
the second
line
and form
3 (the
TAB
form)
for
the third
line.
