☜	IOERRor Draft MDC Standard					☞

3.1.4 IOERROR = expr

expr specifies the I/O error trapping mode.

A value equal to "NOTRAP" specifies that I/O errors on a device do not raise error conditions. A value equal to "TRAP" specifies that I/O errors on a device do raise error conditions with an ecode value associated with the error. Values beginning with Z (or z) are reserved for the implementation. All other values are reserved. Values differing only in the use of corresponding upper and lower case letters are equivalent.

If no IOERROR is specified, the initial I/O error trapping mode for a socket is "NOTRAP".
