>Uhmmm...I think I understand it. I'm more used to simple highly scoped error handlers (VB, VBA,Delphi, Oracle) than VFP's layered approach. I can't think of another language that does it the same way. Anyway, it causes my brain to ache when I'm trying to work out where my error handler is at any one time. I'll get used to it once I've pushed it hard enough.

Fox takes encapsulation a step further. Each object should take care of its own errors. IOW, the errors should be handled locally if possible, if not, pass it up using dodefault() which would eventually call the .parent.error etc. Pretty much like medicine - handle easy cases on the spot, send the rest to a doctor, and the doctor may pass them further up to surgery, which may eventually handle the worst cases.
