I have the following:
"10.6.1 Numeric editing"
"The I, B, O, Z, F, E, EN, ES, D, and G edit descriptors may be used to specify
the input/output of integer, real, and complex data."
[...]
"(6) On output, with I, B, O, Z, and F editing, the specified value of the
field width w may be zero. In such cases, the processor selects the smallest
positive actual field width that does not result in a field filled with
asterisks. The specified value of w shall not be zero on input."
Thus it looks valid also for non-integers. However, going on one finds that the
B, O, & Z edit descriptors are only mentioned in "10.6.1.1 Integer editing"
whereas "10.6.1.2 Real and complex editing" starts with "The F, E, EN, ES, and
D edit descriptors specify the editing of real and complex data. [...] The G
edit descriptor also may be used to edit real and complex data."
Thus, combining the two, using BOZ edit descriptors is invalid in F95/F2003.
How about F2008? The first quote is essentially the same but one finds there:
"10.7.2.3 Real and complex editing": "The G, B, O, and Z edit
descriptors also may be used to edit real and complex data (10.7.5.2.2,
10.7.2.4)."
