This is what you wrote me on 7 July:

Mac OS 9 they're not necessary, they are on OS X and Windows).

It happened months, if not years ago, and I've stuck with 
three-character extensions ever since.  What I need is to  create a 
list of these "truths" and retest them every six to ten months to see 
if I'm still correct.
