FORMAT
Statement
Input
Specifications
The
FORMAT
statement permits you to
determine
how
you
want
the
results
of
com-
putations to look
in
the
output
data
and
allows you to tell
the
processor
how
input
data
is to
be
read
from cards, tape,
or
typewriter.
In
both
instances, you
are
con-
cerned
with
the
problem of converting
data
from either its external form
(cards,
tape,
typewriter)
to
an
internal form
(core
storage),
or
from its internal form to
cards,
paper
tape, or
the
printed
line.

Example:
"FORMAT

S2,
S.l,

,
Sn)"
where
s],
SQ,
S.l
and
Sn
are
specifications as described below.

Description
Fixed
point
numbers
Floating point
numbers
without
an
exponent
Floating
point
numbers
with an exponent
where
w is
the
width
of
the
field
(that
is,
the
total
number
of positions
printed
or
punched)
and
d is
the
number
of decimal places as explained
in
the
follow-
ing
paragraphs.
All
three
forms
can
be
used
in
FORMAT
statements for
both
input
and
output
statements. However,
there
is
a slight difference in
the
meaning
between
an
input
and
an
output
specification,
so
they will
be
described separately.
The
FORMAT
statement
may
be
written anywhere in
the
source program.
An example of
card
input
is used here,
but
the
principles illustrated also
apply
to
paper
tape
records
and
to
typed
input.
