Change the position indicator in a file.
STATUS = FSEEK(FID, OFFSET, ORIGIN) repositions the file position
indicator in the specified file to the specified byte offset with
respect to the specified origin.
FID is an integer file identifier obtained from FOPEN .
OFFSET values are interpreted as follows:
> 0 Move toward the end of the file.
= 0 Do not change position.
< 0 Move toward the beginning of the file.
ORIGIN values are interpreted as follows:
'bof' or -1 Beginning of file
'cof' or 0 Current position in file
'eof' or 1 End of file
STATUS is 0 on success and -1 on failure.
