You probably mean '%PATHEXT'. Mine is:
  .COM;.EXE;.BAT;.BTM;.CMD;.JS;.JSE;.WSF;.WSH;.MSC;.tcl;.py;.pyw;.pl;.htm;.html

In my favourite shell 4NT, I simply can have:
   set .py=python

Instead of the Explorer associations that the Python-installer puts
in my registry. Revealed from my shell:
   c:\> assoc .py
    .py=py_auto_file
   c:\> ftype py_auto_file
    py_auto_file="F:\ProgramFiler\Python27\python.exe" "%1"

In ShellExecuteEx(), what program gets launched for "py_auto_file" in this
case, seems to be determined by the 'SHELLEXECUTEINFO:lpClass' member.
I fail to see that Python uses this structure anywhere.
