The Display  Tape Size command  displays or  lists an approximation  of
how much  data has been written to  a tape.  Each file  is listed along
with  a total.   An outfile is  optional.  Hardware  compression is not
considered.  DSPTAP  is used to determine  the information.  Because  a
spooled  file  must be  read,  only lower  and  upper  case English  is
supported.

If  an outfile is requested,  the model file is  TAATAPTP with a format
name of TAPRCD.

If there  are many files  on the  tape, DSPTAPSIZ  can be  a very  slow
running command.

A typical command would be:

             DSPTAPSIZ   DEV(xxx)

The  tape (or  virtual  device)  is used  with  the  DSPTAP command  to
output a  spooled file.  The spooled file would  then be converted to a
QTEMP file  and the  file read  and printed  as a  spooled file.    The
spooled file is then displayed.

DSPTAPSIZ escape messages you can monitor for
---------------------------------------------

None.  Escape message from based on functions will be resent.

DSPTAPSIZ Command parameters                          *CMD
----------------------------

   DEV           The device where the media exists.

   ENDOPT        The  end of  tape  option.   The  default is  *REWIND.
                 *UNLOAD may also be specified.

   OUTPUT        How  to  output the  results.   *  is  the default  to
                 display  the spooled  file if  the command  is entered
                 interactively.  The  spooled file is deleted  after it
                 is displayed.

                 If  the  command is  entered  in  batch  or *PRINT  is
                 specified,  the spooled  file is output  and retained.

                 *OUTFILE may be specified to  output a data base  file
                 with one record per label.

   OUTLIB        The  library  in  which  the   file  TAPSIZP  will  be
                 placed.   The default is  *LIBL.  If  the TAPSIZP file
                 does not already exist,  a library must be  specified.

   OUTMBR        The member  of the TAPSIZP  file to be  used.  If  the
                 member does  not exist, it  is added.   The default is
                 TAPSIZP.

   REPLACE       A  *YES/*NO  value for  whether  the member  should be
                 cleared before writing records  into it.  The  default
                 is *YES.
