In fact, now that I think of it... I just looked at some old school papers I had tucked away in a family album. I'm quite sure that in grammar school, I was tought to use a date format of 8/9/79, without leading zeros. I can't prove it, of course, but feel fairly sure that the prevalence of leading zeros in dates occured only in the mid to late 1980's as computers became more prevalent in our society (no doubt because thousands of cobol programmers writing business apps needed a way to convert dates as strings to numbers that was easy and fit in small memory). Assuming I'm right about that, then the use of a leading 0 to represent octal actually predates the prevalence of using 0 in dates by almost two decades. And while using leading zeros in other contexts is "familiar" to me, I would certainly not consider it "common" by any means. Thus I think it's fair to say that when this syntax was selected, it was a rather good choice. -- Derek D. Martin http://www.pizzashack.org/ GPG Key ID: 0x81CFE75D
