D'oh... okay, people (including me) are reading others' posts with
preconceptions about what they are talking about in mind.
The PATHEXT thing is required to be able to type just "scriptname"
_without_ the .py extension. Alternatively, it appears there's yet
another obscurely documented feature involving setting environment
variables that resemble file extensions, as posted by others. (Where do
these things come from? It's like Microsoft releases the OS, then
periodically sends private emails to random people, pointing out obscure
new features, so that they can tell others in some feeble effort to make
using Windows look like a grassroots effort or something. How are
regular mortals supposed to find out about things like "set .py="?)
The ability to run the script with just "scriptname.py" comes from, I
believe, having a file association set up with "ftype" and "assoc" or
the equivalent registry entries. For this to work from _any_ location
one must have the folder containing the *script* in the PATH, as with
any executable, while the path specified by FTYPE points to the Python
executable. (This ftype/assoc file association is set up by the
standard installer, which is why it works for BartlebyScrivener).
