Russ,
Just a quick note about bugs that don't get fixed... one of the nice things about Object heirarchy is the ability to roll your own objects which can also correct bugs.
For example there is a current issue with the date class that might return incorrect values if the current dBASE dateSetting is not "MDY". US developers can stop reading here :-)
One method of dealing with this would be to add a custom date class that fixes the problem on the fly. dDate = new MyDate() instead of Date().
Within MyDate the dateSetting is set to "MDY" before calling the method within the original Date class.... and then reverts to the original dateSetting before returning the answer.
Ok, it's a pain to setup but it only needs to be done once. You've fixed the bug yourself, instead of having to remember it or risk being tripped up again and again.
This ability, of course, is absent in dBASE IV. However, your original point is still valid, because you can't fix ALL bugs that way.
Regards,
Andy
