CALL FSeek(Unit, Offset, Whence, ErrLab)
Unit: INTEGER
; scalar; INTENT(IN).
Offset: INTEGER
; scalar; INTENT(IN).
Whence: INTEGER
; scalar; INTENT(IN).
ErrLab: *
label, where label is the label
of an executable statement; OPTIONAL.

Description:
Attempts to move Fortran unit Unit to the specified Offset: absolute offset if Whence=0; relative to the current offset if Whence=1; relative to the end of the file if Whence=2. It branches to label ErrLab if Unit is not open or if the call otherwise fails.
