tkey(1)                          DG/UX 5.4.2                         tkey(1)


NAME
       tkey - set label and data translation parameters

SYNOPSIS
       tkey [ -d ] [ -f filename ] [ -p pseudo ] [ key = val ... ]

DESCRIPTION
       Tkey modifies file labels and record translation parameters.  If
       write label parameters are modified, they will be remain in effect
       only until the next tposn or twrite command (tposn and twrite reset
       write label parameters to their default values).  If you would like
       the write label values to remain in effect for multiple twrite
       operations, use the -d option.

   Options
       -d          "Default." Resets the default write labels according to
                   the keyword assignments provided.  If this option is
                   specified, changes to the write labels will remain
                   effective for any succeeding commands in the access
                   session.  If -d is not specified, the changes to the
                   write labels will affect only the command which
                   immediately follows tkey.

       -f filename "Keywords." The file filename contains the keyword
                   assignments.  See reelexchangeintro(1) for more
                   information on the format of this file.

       -p pseudo   "Tapesetname." Tapeset pseudo name as specified by the
                   preceding taccess command which initiated access to the
                   tapeset.

       key = val   "Keywords." Set keyword key to value val.  For
                   information about keywords and values, see
                   reelexchangeintro(1).

EXAMPLE
       tkey blen = 8192

       sets the block length to 8192 bytes (possible range = 1 to 32760).
