NAME

     compsort  - output sorted traces (elastic processing)

SYNOPSIS

     compsort [ -Nntap ] [ -Ootap ] [ -ntable  ]  [  -eiend  ]  [
     -lnst ] [ -mnend ] [ -HwrToStUn ] [ -HwsToTmAU ] [ -G ] [ -S
     ] [ -D ] [ -R ] [ -X ] [ -0 ] [ -V ] [ -? ]

DESCRIPTION

     compsort generates sorted traces from the input data set and
     the  appropriate  entry  from  the sort table generated from
     presortc

     compsort gets both its data and its parameters from  command
     line  arguments.  These arguments specify the input, output,
     end time, sort table, sort type, renumber option,  and  ver-
     bose printout, if desired.  compsort emits the sorted m

  Command line arguments
     -N ntap
          Enter the input data set name or file immediately after
          typing  -N  You cannot pipe data into compsort since it
          requires data on disk within which to move a pointer (a
          pointer cannot exist in a sequential pipe).  This input
          file should include the complete path name if the  file
          resides    in    a    different   directory.    Example
          -N/b/vsp/dummy tells  the  program  to  look  for  file
          'dummy' in directory 'vsp' stored on the 'b' disk.

     -O otap
          Enter the output data  set  name  or  file  immediately
          after typing -O.  This output file is not required when
          piping the output to another process.  The output  data
          set also requires the full path name (see above).

     -n table
          Enter the name of the sort table generated by presortc.

     -e iend
          Enter the end time of the output traces in ms  (default
          = last sample)

     -l nst
          Enter the start index to be output, i.e. if  -D  option
          (cdp sort) was specified then nst will be the first cdp
          output  (default = first index)

     -m nend
          Enter the last index to be output  (default =  last  on
          input)


     -Hwr TrWrdr
          Enter the  receiver  component  header  word  mnemonic.
          Default  =  ToStUn.   The code reads: 3 = vertical, 1 =
          crossline, 2 = inline).

     -Hws TrWrds
          Enter  the  source  component  header  word   mnemonic.
          Default  =  ToTmAU.   The code reads: 3 = vertical, 1 =
          crossline, 2 = inline).

     -G -S -D -R -X
           -G causes common receiver sorted traces to be  output;
          the output record numbers are set to the GI index.
           -S causes common source sorted traces  to  be  output;
          the output record numbers are set to the source index.
           -D causes common depth sorted traces to be output; the
          output record numbers are set to the CDP index.
           -R Include on command line if distance (common offset)
          sort is desired with a zero trace pad

      Include on command line if distance (common offset) sort is
     desired with no zero trace pad

     -0   Include on command line if out traces and  records  are
          to  retain  their original numbers in positions 107 and
          106 of the trace header.

     -V   Enter the command line argument '-V' to get  additional
          printout.

     -?   Enter this (or '-?' if you are running in  c-shell)  to
          get  online  help.   The  program  will terminate after
          printing this.
