NAME

     arcsstack  - module to generate Pilot and Object Stacks  for
     input to arcscross for determination of adjacent record cum-
     mulative statics.fR

SYNOPSIS

     arcsstack [ -Nntap ] [ -Oprefix ] [ -Pptap ] [ -nsnstr  ]  [
     -nenend  ] [ -rsnrst ] [ -renred ] [ -shot ] [ -group ] [ -V
     ] [ -? ]

DESCRIPTION

     arcsstack  reads  in  either  shot  or  group  sorted  input
     records,  forms  a  Pilot and Object stack with an option to
     remove a structural term prior to  stack  and  outputs  said
     stacks for input to  arcscross  .

     arcsstack gets both its data and its parameters from command
     line  arguments.  These arguments specify the input, output,
     the start and end traces, the start  and  end  records,  the
     sort  order  of  the  input dataset and verbose printout, if
     desired.

  Command line arguments
     -N ntap
          Enter the input data set name or file immediately after
          typing  -N. 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 '/b/vsp'.  If this  entry  is
          not present input is expected on stdin.

     -O otap
          Enter the output data set prefix immediately after typ-
          ing  -O.  This  output  prefix allows one to output the
          Pilot  and  Object  stack datasets to a directory other
          that  the one where the job was initiated.  This prefix
          will precede the output filenames  which  also  reflect
          the  sort  domain  of  the  input data.  If  -group  is
          present on the command line [see below] then the output
          files  would  be   prefixGroupPilot and  prefixGroupOb-
          ject.  If  -shot  is present on the command  line  then
          the output files would be  prefixShotPilot and  prefix-
          ShotObject. You cannot pipe out of this process.

     -P ptap
          Enter the input XSD structural  header  value  at  pick
          location  file.   This  file should contain information
          for every trace of the control  stack  and  the  header
          mnemonic   DphInd   must  have  been  flagged.   If not
          present, no structural correction will be made prior to
          generation  of the  Pilot  and  Object stacks.  You may
          pick as many structural horizons that  you  wish.   You
          may  pick  from  left  to right or right to left.   You
          must include a pick for the first and last trace of the
          stack.   You  must  also detect output a value at every
          trace when generating the header value at pick location
          file.  The  structure picks must be made from top down.
          Arbitrary positioning of structural control will  break
          this code.

     -ns nstr
          Enter the start trace number.  The default is the first
          trace of the record.

     -ne netr
          Enter the end trace number. The  default  is  the  last
          trace of the record.

     -rs nrst
          Enter start record number.  Default value is the  first
          record.

     -re nred
          Enter end record number.  Default value is last record.

     -shot
          Enter the command line argument  -shot   if  the  input
          data is in common shot sorted order.

     -group
          Enter the command line argument  -group  if  the  input
          data is in common receiver sorted order.

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

     -?   Enter the command line argument '-?'  or   -h   to  get
          online  help.   The  program  terminates after the help
          screen is printed.
