NAME

     auto  - compute auto correlation of traces

SYNOPSIS

     auto [ -Nntap ] [ -Ootap ] [ -Llags ] [ -nsnstr ] [  -nenetr
     ] [ -rsnrst ] [ -renred ] [ -V ] [ -? ]

DESCRIPTION

     auto computes the autocorrelation of  a  selected  range  of
     input traces.

     auto gets both its data and its parameters from command line
     arguments.   These  arguments specify the input, output, the
     desired number of lags, the start and end traces,  and  ver-
     bose printout, if desired.

  Command line arguments
     -N ntap
          Enter the input data set name or file immediately after
          typing -N unless the input is from a pipe in which case
          the -N entry must be omitted.  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'.

     -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).

     -L lags
          Enter the number lags of the autocorrelogram  you  wish
          to compute.  This will be the output trace length.

     -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.

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

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