I have a program I want to distribute. I have it in a couple sample installations. In this program
there is a form that is simply a listbox displaying records from a table. These records are in date
order. I need to be able to switch the order from sequential to reverse sequential.

I have one index ascending on this file. On the form right now, the file is listed in the DE and the
ORDER is set for this index. What is the best way to switch this once I create a button
to control the switch?

Should I add a second index to the file? If I do, how do I programatically do it for installed
installations? I suppose in my MAIN.PRG file I can check to see if the new index exists and if
it doesn't I can create it somehow - how do I check, how do I create it?

Should I just control it programattically in the form? How?
