NAME
     tell - Return current access position for an open channel

SYNOPSIS
     tell channelId


DESCRIPTION
     Returns an integer string giving the current access position
     in channelId.  This value returned is a byte offset that can
     be passed to seek in order to set the channel to a  particu-
     lar  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.
