I guess what gets me about VFP arrays is that there isn't such a thing as an empty one. When you initialize an array, it comes with a single element, initialized to .F. So when you go to populate it, you have to have special code to either not redimension it for the first element, or to remove the bogus extra element after you are done populating. Other than that, an array index is fundamentally an offset from the beginning. 0-based preserves that relationship, so that the first element has no offset, the second element is offset by 1, etc. Do you commonly find yourself writing code like: alen(aTemp, 1) - 1 ? If so, that indicates that 0-based would be better. On the other hand, in Python I sometimes need the natural index, most likely to display to the user, so I end up doing: idx + 1 -- pkm ~ http://paulmcnett.com _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[EMAIL PROTECTED] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
