DESCRIPTION
       Returns  an  integer string giving the current access position in chan- |

       in  order  to set the channel to a particular position.  Note that this |
       value is in terms of  bytes,  not  characters  like  read.   The  value
       returned is -1 for channels that do not support seeking.
