Foxpro does have XML support, so you answered that part of my question, thanks.
And it is capable of calling any other executable on the local machine through 
local OS shell - which seems to be what you are advocating. But I'm not sure how
I would do that over the internet. I just discussed this issue with Larry, and 
I assume
that I would use HTTP? Or is there a way to call a command line script on a 
web server without using HTTP?  Sorry if this is a stupid question.

Thanks for your help!
