I have tried MicroPython a little, but managing the subtle differences tends to throw me, especially since I update DOS scripts only irregularly. The LFN issue is funny! I do know that the older available PYTHOND.EXE also returns >>> ImportError: No module named encodings on `import encodings` unless I run DOSLFN.EXE beforehand. I think I understand that your *nofreeze.exe is the fast version of the application, and requires DOSLFN, the standard library in a separate directory structure, and specified with %PYTHONPATH% for `import encodings` to work. Anyway, your *freeze.exe application has no external dependency aside from standard DPMI extender, is portable, and is great for my usage. Half a minute to start up in a virtual environment is perfectly fine, since I develop the system administration scripts on a more modern machine anyway.
