I misspoke yesterday when I said that Stata searches from the
beginning of the filename. For the purposes of determining
whether a file has an extension, it does not matter whether the
search starts at the beginning of the filename or at the end.
If there is a period anywhere in the filename, Stata will assume
the file has an extension. Thus, if a user types
. use directors.tenure.proxy.sep2005
Stata will assume that the extension is "sep2005" and will not try
to add ".dta".
