I am writing a chunk of code in which I want to trap I/O errors.  I
use END= and ERR= specifiers to do this.  Logic tells me that an
end-of-file condition should be handled by an ERR= iff no END= is
present.

The '77 standard tells me that "The set of input/output error
conditions is processor dependent." That seems to give someone the
leeway to *not* handle end-of-files with ERR= if no END= is present,
and (of course) I have a case in which this occurs (SunOS 3.4 f77).

Can anyone tell me if this "hole" was intentional, or an oversight?
If it was intentional, what is the logic?  It seems rather inane to
have to put in "END=8800, ERR=8800" into every READ statement.
