I have an application to support. Application was made with VFP 6.

I have all the source code but no real docs with it.

Where should I begin, to figure out the most out of that application?

Is the documenting wizard in VFP enough?

Is there something better with the documenting wizard in VFP7 (which I have) or VFP8 (Which I don't have yet)?

Are there better tools out there for VFP that would help figure out the ins and outs of the source code?

I guess that amongst the most important things to do is to find out where the fields for all the table are used?

Any suggestions on things that I forgot to mention?
