One of the following identifiers or corresponding values: (n)
Ignore the POSITION qualifier.
Position to the first record in the file (relative to the key of reference, if it’s an ISAM file).
Position to the last record in the file (relative to the key of reference, if it’s an ISAM file). (Windows, UNIX only)

Discussion
The POSITION qualifier sets the file position before performing the I/O operation.
By default, the OPEN statement positions to the first record in the file. OPEN only recognizes the Q_FIRST and Q_EOF identifiers.
The FIND statement only recognizes the Q_FIRST, Q_LAST, and Q_BOF identifiers.
The READ statement only recognizes the Q_FIRST and Q_LAST identifiers.
For non-ISAM files, the WRITE statement only recognizes Q_FIRST, Q_LAST, and Q_EOF identifiers.
