Common sense is enough ... Just look at how much revenue you can make per user per year (about $600), thus how many users you need to pay your bills, time, advertisement, rental, clerks, your work and make profit.

Can't tell you where we got the number of developers from, what I can tell for sure it's conservative. Nothing to do with the number of licenses sold.

Though I'm sure the Fox team has made some research on 'real' developer counts, I doubt they chose the good rationale to defend VFP against those at ms who had wanted, for almost 10 years, to kill it.

>I don't have any. I don't have the staff to do such world wide market research. But the number you propose is absolutely not believable. Could there be 150,000,000 PCs running some form of a VFP app? Let's say that's the number. But I can't believe that a VFP app was the driving factor that caused those PCs to be purchased.

>>>So, you're attributing the sales of 150,000,000 copies of Windows directly to VFP? That's pure bullsh*t.
