<div>
<p>2.<span style="font-size:7.0pt"> </span>Have we added any other capability. For instance, I would love to present a list of variables to be calculated and let my user select or unselect each to decide exactly what he wants as output. With a numeric
field with 0 as unselect and 1 as select, people will always manage to type something else in there. If this interface could have a checklist, or if fields could have a drop down list (Yes/No, etc) then this would greatly expand the utility of this technique.<o:p></o:p></p>

<p class="MsoNormal">You can do this if you have a fixed number of variables. Just list each variable option as a IntVectorProperty with a BooleanDomain in the XML. In the input file for the filter generator, just express these options with the default values,
