FSeek Intrinsic
...............

     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.

Intrinsic groups: `unix'.

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.
