Ditto... well only 18 years on foxpro :)

Just received Ed feedback on the subject. I'll post an announcement
for DABO on UT to-day on Dabo team's behalf.

I've come thru the the same experience. The recent addition of
decimal and datetime support will definitely help vfp-ers.
Thanks to the python developpers for this.

The VFP db-aware UI side is missing. Let us hope Dabo will fill
part of the gap.

Well ... "ReportLab" is a code-based reporting tool, not a db-aware
visual tool "à la crystal" . It clearly does fit the bill at this stage as
a replacement for the vfp report writer. A wx* visual report writer
would be a great addition to wxpython. I've not heard of any at
this stage.
