Hi Paul! You want to test them all? <g> Probably no one (and M$ guys too) can tell us something useful about this topic. I was on M$ site and searched whole KB, but no luck <g>... But I must agree with your point of view. Another note: the limitations of most functions are inherited from common VFP limits like 255 chars per fieldname etc... >You know, there are many functions that take a string parameter and that >doesn't mean they accept the maximum length. Some of these > anywhere the maximum length.
