Regarding the comment that month-day-year is better because it presents "most inportant information first", I'd like to point out that telephone numbers are presented as Country code - area code - local number or (Area code) local number, and somehow, when the country code and area code are in fact the local defaults, people are able to rapidly scan forward to the local number, automatically focusing on the information which is locally important. Thus, I have great difficulty accepting the contention that it is somehow bad human engineering to use root -> leaf form when specifying a point within a hierarchical address space; it appears that a human mechanism exists which allows a very efficient scan of the higher-level information. In left-to-right languages such as English, there is a significant probability that failing to use this form will result in the scan halting once the local information has been processed, without continuing on to verify the higher-level information. Making the assumption that the higher-level information does not need to be scanned, the lower-level information is put to immediate use. This results in "human error"; the form which requires that the higher-level information be scanned, even automatically, is less likely to result in this "unverified assumptions" error. We now question the defenders of non-hierarchical presentation as to how a form which tends to promote human error represents an advance in human engineering. Bill Wolfe

According to wtwolfe@hubcap.UUCP (Bill Wolfe): >I'd like to point out that telephone numbers are presented as > Country code - area code - local number >or > (Area code) local number, > >and somehow, [...] people are able to rapidly scan forward >to the local number, automatically focusing on the information >which is locally important. This is true. However, the usual representations of phone numbers include hypens and parentheses, which ease rapid and accurate parsing. A simple set of numbers with nothing but spaces to separate them is more difficult to parse than one with punctuation. -- Chip Salzenberg <chip@ateng.uu.net> or <uunet!ateng!chip> A T Engineering My employer may or may not agree with me.
