FORTRAN-80
If
the file
is
being connected for formatted
110,
'reclen'
is
the
number
of
characters.
If
the file
is
being connected for
unformatted
110,
the length
is
measured in bytes.
If
the file already exists, the length specified must be
that
used when the file was
created. In the case
of
a new file, the processor creates a file with the specified length
for each record.
The
REeL
specifier must be included in the
OPEN
statement when a file
is
being
connected for direct access.
Example:
OPEN
(3,
FILE='CARDS',
STATUS='NEW',
ACCESS='DIREcr,
& FORM = 'FORMATTED',
RECL=80)
6.2.1.9
Blank Specifier
The
format
of
the blank specifier
is
BLANK
=
blnk
where
'blnk'
is
one
of
the character constants
'NULL'
or
'ZERO'.
If
the BLANK
specifier
is
omitted, the default value
is
'NULL'.
If
'NULL'
is
specified, all blanks in numeric
formatted
input
fields are ignored, ex-
cept
that
a field
of
all blanks has the value zero.
If
'ZERO'
is
specified, all blanks ex-
cept leading blanks have the value zero.
The
specifier
is
permitted only for files being connected for formatted
input/output.
Example:
OPEN
(UNIT=3,
FILE='TOTALS',
STATUS='NEW',
&
FORM='FORMATTED',
BLANK='ZERO')
