Jerry, can you have a look? Using ifort it prints: 2003.000
and it seems to be valid Fortran 95/2003.
"10.7.6 BN and BZ editing"
"The BN and BZ edit descriptors temporarily change (9.4.1) the blank
interpretation mode (9.4.5.4, 9.5.1.5) for the connection. The edit descriptors
BN and BZ set the blank interpretation mode corresponding to the BLANK=
specifier values NULL and ZERO, respectively. The blank interpretation mode
controls the interpretation of nonleading blanks in numeric input fields. Such
blank characters are interpreted as zeros when the blank interpretation mode
has the value ZERO; they are ignored when the blank interpretation mode has the
value NULL. The effect of ignoring blanks is to treat the input field as if
blanks had been removed, the remaining portion of the field right justified,
and the blanks replaced as leading blanks. However, a field containing only
blanks has the value zero.
"The blank interpretation mode affects only numeric editing (10.6.1) and
generalized numeric editing (10.6.4.1) on input. It has no effect on output."
"9.4.5.4 BLANK= specifier in the OPEN statement
"The scalar-default-char-expr shall evaluate to NULL or ZERO. The BLANK=
specifier is permitted only for a connection for formatted input/output. It
specifies the current value of the blank interpretation mode (10.7.6, 9.5.1.5)
for input for this connection. This mode has no effect on output. It is a
changeable mode (9.4.1). If this specifier is omitted in an OPEN statement that
initiates a connection, the default value is NULL."
Thus it should work with default settings. Not surprisingly (as g77 works),
BZ/BN are also part of Fortran 95.
