File positioning mechanisms are a fundamental part of building indexed record oriented files and managing fixed length records and fields in a sequential and variable length file structure.

The position control takes an integer value that selects a reference technique for setting the new position value.

A position control value of 0 (zero) indicates the new position should be measured from the start of the file.

A position control value of 1 adds the offset to the current position. This should allow forwards or backwards movement relative to the current position.

A position control value of 2 is measured relative to the end of the file.
