POSIX Subroutine: Modifies a file position.
CALL PXFFSEEK (lunit,ioffset,iwhence,ierror)
If successful, ierror is set to zero; otherwise, an error code. Possible error codes are:
EINVAL: No file is connected to lunit, iwhence is not a proper value, or the resulting offset is invalid.
ESPIPE: lunit is a pipe or FIFO.
EEND: The end of the file has been reached.
The PXFFSEEK subroutine modifies the position of the file connected to unit lunit.
