Indeed, but on most cases, log2vis is a quite-good approximation to vis2log. IIRC I once used this fact for some real, simple, dataset, and the results were just fine. Do note that vis2log is not a function, in the mathematical sense - there are cases of two different "logical" strings that log2vis maps to the same "visual" string. So a potential vis2log would have to either make a guess or return all possible results, or some other such kludge. In reality, if you kept important data in visual form, you might have a problem, and need to manually fix things, after running some approximation (such as log2vis). -- Didi ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
