NAME

     arms  - module to compute average or rms of traces

SYNOPSIS

     arms [ -Nntap ] [ -Ootap ] [ -nsnstr ] [ -nenetr ] [ -rsnrst
     ] [ -renred ] [ -A ] [ -V ] [ -? ]

DESCRIPTION

     arms computes the average or the rms of a selected range  of
     records and traces.

     Arms gets both its data and its parameters from command line
     arguments.   These  arguments specify the input, output, the
     start and end records, the start and end traces, average  or
     rms calculation, and verbose printout, if desired.  The out-
     put data set will consist of 1 trace.  A good application of
     arms is to compute a single agc gain curve from the optional
     output of davc.

  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/vsp/dummy tells the program to look for file
          'dummy' in directory '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).

     -ns nstr
          Enter the start trace number.  Trace numbers below this
          value will not be processed.  The default is 1.

     -ne netr
          Enter the end trace number.  Trace numbers  above  this
          value  will  not be processed.  The default is the last
          trace number on the input data set.

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

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

     -A   If present compute the average, otherwise  compute  the
          rms.

     -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.
