Steve Lionel points at the following:

"If an error condition occurs during execution of an INQUIRE statement, all of
the inquiry specier variables become undened, except for variables in the
IOSTAT= and IOMSG= speciers (if any)."

Thus, if the RECL of the connection is larger than huge(kind(recl_var)), one
has to raise an error.

The question is only how the default should be handled. As written, I do not
really understand the current algorithm. Namely, whether we effectively
implement huge(0_int64) by extending the chunks. Or whether we apply a lower
boundary by default.

Additionally, we have the problem that the internal IO descriptor is only of
kind int32 (cf. PR 44292).
