>Anybody know the first version of Fox to have the DTOS() function?

It's been at least since 2.0; I don't have any earlier copies around. I'd be willing to bet that it's actually from back in the FoxBase+ days, but that's a guess.

You might want to check Communications Horizons, the people who put out Y2KFox; if anyone would have a definitive answer, I'd be inclined to think they'd know, since DTOS() is one of the biugger Y2K issues them. Digital Coyote would be another reliable source of information.
