INQUIRE: NEXTREC Specifier

The NEXTREC specifier asks where the next record can be read or written in a file connected for direct access. It takes the following form:

NEXTREC = nr

nr

Is a scalar integer variable that is assigned a value as follows:

If the file is connected for direct access and a record (r) was previously read or written, the value assigned is r + 1.
If no record has been read or written, the value assigned is 1.
If the file is not connected for direct access, or if the file position cannot be determined because of an error condition, the value assigned is zero.
If the file is connected for direct access and a REWIND has been performed on the file, the value assigned is 1.
