The

the

is

stl

specification list whose items

are

separated

by

commas

Each

item in

'flist'

must

be a

repeatable

edit

descriptor,

a

nonrepeatable

edit

descriptor,

or

a

parenthesized

'flist.'

An

edit

descriptor

is

repeated

by prefixing it

with a

nonzero,

unsigned integer

constant

called a

'repeat

specification.'

The

entire

'flist'

can

also be prefixed by a

repeat

specification.

Note

that

the

statement

with

no

'flist'

specified,

'FORMAT

can be

used only

if

the

110

list

is

also

empty.

Conversely,

if

the

110

list

is

not

empty,

'flist'

must

have

at

least

one

repeatable

edit

descriptor.

6.4.3. t Edit Descriptors

6.4.3.1.1

Repeatable

Edit

Descriptors.

Repeatable

edit descriptors generally consist

of

a letter indicating the type

of

data

involved

and

a

number

indicating

the

size

of

the

data

field

and

how

it

is

to

be divided.

The

repeatable

edit descriptors are:

The

are

used

to

F

input;

E allows

in scientific

notation.
