Oleg Broytmann Institute for commercial engineering phd@ice.ru Programmers don't die, they just GOSUB without RETURN. Here I am providing a few patches and new modules for python library, mostly for DOS. lib/dospopen.py - popen() for DOS lib/os.py - include test for popen() and definition for popen for DOS lib/rexec.py, lib/FileWrapper - I split rexec.py and extract FileWrapper (similar to UserList and UserDict) lib/tempfile.py - patched tempfile compileall.diff - fix an error when compileall does not compile anything in DOS due to incorrect case of file extension. tempfile.diff - add test for env vars TEMP and TMP (most useful in DOS) and change template for DOS temp file to "~pyXXXX" test/filewtst.py - test program to test FileWrapper test/popentst.py - test program to test popen() for DOS
