NAME

     hdrswap  - transfer trace header info from one data  set  to
     another

SYNOPSIS

     hdrswap [ -N1ntap1 ] [ -N2ntap2 ] [ -Ootap ] [ -whdrwd  ]  [
     -V ] [ -? ]

DESCRIPTION

     hdrswap takes trace header information from data set  2  and
     puts  it  into  the trace headers of data set 1.  Either the
     entire header or just one header word can be transferred.

     hdrswap gets both its data and its parameters  from  command
     line arguments.  These arguments specify the inputs, output,
     and the optional  header  word,  and  verbose  printout,  if
     desired.

  Command line arguments
     -N1 ntap1
          Enter the input primary data set name or  file  immedi-
          ately  after typing -N1 unless the input is from a pipe
          in which case the -N1  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'.

     This is the data that will be passed  to  the  output  after
     trace header alteration.

     -N2 ntap2
          Enter the secondary data set name.  This  is  the  data
          set  from  which  the  trace header information will be
          taken.  If this program is run  in  the  standard  UNIX
          environment  this data set cannot be piped.  If this is
          run inside ikp then this data set is  labelled  "3"  on
          the process box.

     -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).

     -w hdrwd
          Enter the header word mnemonic to transfer, e.g. header
          word  DstSgn (signed trace distance).  If none is given
          on the command line the entire trace header  from  DSN2
          will be transferred to DSN1


     -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.
