NAME

     xcram10     -    graphical    interface    for    unattended
     reading/writing of data on multi-volume robotics devices.

SYNOPSIS

     xcram10 [ -r ] [ -b ] [ -g ] [ -segy ] [ -mvs ] [ -V ]

DESCRIPTION

     xcram10 is a utility to provide read/write access to devices
     utilizing multiple media volumes.

INPUT

     xcram10 gets both its data and parameters from the UNIX com-
     mand line.

  Command line arguments
     -r   Enter to read data from a device or devices.

     -b   Enter blocksize to use. NOTE: xcram10 handles blocksize
          internally so that if you are reading a file previously
          written using cram or xcram default this entry. It is a
          good practice to always default this entry when writing
          to tape. (Default blocksize = 32768)

     -g   Skips a header on subsequent tapes based on the initial
          green  word  read  from  the tape. This is particularly
          useful for  maintaining  independent  USP  datasets  on
          multi-volume  sets,  but  retaining the ability to read
          all of them in together as one data stream.

     -segy
          Assumes that subsequent  tapes  have  a  standard  3600
          bytes SEGY header which is to be bypassed.

     -mvs Assumes that subsequent tapes have a standard MVS  tape
          label  and an end-of-tape marker which is to be skipped
          over.

     -V   Verbose  option.   Creates   a   file   of   the   form
          XCRAM10.nnnnn  where nnnnn is the process id containing
          information on the media processing.

DISCUSSION

     xcram10 uses the standard UNIX redirection symbols for stdin
     and stdout.

          xcram10 -r > OutPut_File

          xcram10 < InPut_File

     You may also choose to pipe into or out of the process.  For
     example,  say you have a multi-volume dataset to read into a
     job:

          xcram10 -r | job.name

     or you may have data comming out to tape that will more than
     fill one cassette:

          job.name | xcram10

     or you may just want to process tape to tape:

          xcram10 -r | job.name | xcram10


     Xcram10 will initially come up with a  panel  which  enables
     the  user  to  pick from any robotics device that the media-
     changer software knows about. Multiple volumes from multiple
     devices are available for selection if configured. After all
     volumes to be read/written are selected, processing  may  be
     started  immediately  of  delayed until a specified date and
     time. Each volume is read  in  the  order  selected  and  is
     unloaded after being processed. A history of load/unloads is
     maintained by the program and may  be  viewed  at  any  time
     under the Misc heading of the menu bar.

     More detailed instructions are  available  via  help  panels
     contained within the program.
