A number of Data Control API plugins are provided with SuperSERVER. You can also use the API to create your own DLL or Shared Object (depending on your platform) for programmatic modification of the cross tabulation results.
There is also some sample code provided with the API to give you guidance on writing your own module.
Once you have created your module, you need to use the
method command in SuperADMIN to apply your plugin to SuperSERVER.
