Interesting question. Have you tried to change the year on your computer?

>The previous thread was a good rehash of what sys(2015) does and what it does not. I'd like to shed some light on it from a different angle - does Fox have a Y2015 bug? Namely, will sys(2015) max out after a while?

>Few years ago we had a series of bugs in various apps reported here on UT when names derived from substr(sys(2015), 2) started returning a string which used to begin with a character for years, and now it began with a zero. Well, it's a couple of years later now, and it returns a _3xxxx now. At this rate, it may run out of alphabet in a few years (maybe in 2015?). I couldn't find how it's calculated and whether the initial underscore is there forever, but it would be nice if someone knows and can tell what will happen after once it returns _999999999?
