NAME

     crossplot  - crossplot values from two datasets.

SYNOPSIS

     crossplot [ -N1sample ] [ -N2trace ] [ -Ootap ] [ -rsnrst  ]
     [  -renred ] [ -min1min1 ] [ -max1max1 ] [ -delta1delta1 ] [
     -min2min2 ] [ -max2max2 ] [ -delta2delta2 ] [ -V ] [ -?   or
     -h or -help ]

DESCRIPTION

     crossplot : was built to provide  a  crossplot  output  that
     could  be  viewed in XSD.  The -N1[] dataset associated with
     the sample axis while the  -N2[]  dataset  values  span  the
     trace  axis.   If the user does not specify the axis parame-
     ters the routine will determine the maximum and minimum data
     values  for  each  dataset and derive a delta value for each
     using the input NumSmp and NumTrc values for each axis.   If
     these  values  are rubbish for a 2D plot [i.e. NumSmp = 1 or
     NumTrc = 1] then you better use  the   command  line  limits
     capability.

     crossplot gets both its data and its parameters from command
     line  arguments.  These arguments specify the input records,
     output, start and end records, the axial limits  and  deltas
     for each axis  and verbose printout, if desired.

  Command line arguments
     -N1 ntap1  [default: stdin]
          Enter the input data set name or file immediately after
          typing  -N1  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'.

  Command line arguments
     -N2 ntap2  [default: none]
          Enter the input data set name or file immediately after
          typing -N2. 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  [default: stdout]
          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).

     -rs nrst  [default: 1]
          Enter start record number.

     -re nred  [default: last record]
          Enter end record number.

     -min1 min1  [default: data derived]
          Enter the minimum value for  the  output  sample  axis.
          This  should  be  the  minimum  value  desired from the
          dataset attached at -N1[].

     -max1 max1  [default: data derived]
          Enter the maximum value for  the  output  sample  axis.
          This  should  be  the  maximum  value  desired from the
          dataset attached at -N1[].

     -delta1 delta1  [default: data derived]
          Enter the value for the sample axis increment.

     -min2 min2  [default: data derived]
          Enter the minimum value  for  the  output  trace  axis.
          This  should  be  the  minimum  value  desired from the
          dataset attached at -N2[].

     -max2 max2  [default: data derived]
          Enter the maximum value for the output trace axis. This
          should  be  the  maximum value desired from the dataset
          attached at -N2[].

     -delta2 delta2  [default: data derived]
          Enter the value for the trace axis increment.

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

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

DISCUSSION

     It is often useful to run scanvol on the input  datasets  to
     predetermine  the  min and max ranges for the axes and enter
     this information on the commandline.  Remember that the out-
     put  size  of  the  crossplot will be the input size of your
     datasets by default.  This is  sometimes  not  a  very  good
     idea.
