>We will be converting some old legacy applications (some foxpro 2.6, some clipper) and we are looking for a program that will help us create some basic documentation (calling tree, variable listing, etc.). There used to be a program distributed with Foxbase+ (I think) called FoxDoc that did this. Any ideas???

There's FoxDoc in Foxpro 2.6. In Visual Foxpro it's called Documentation Wizard.
