Thanks for your help guys. Unfortunately both ideas will not work. I guess I should have mentioned that the batch file in question is vsvars32.bat, from the Visual Studio installation directory. I should not modify this file, nor can I create a "wrapper" batch file as you suggested, since I call several other batch files at different times. There's about 6 other nmake calls I make that each is preceeded with a call to vsvars32.bat. For now I'm using the && DOS operator, this seems to work, however it is not ideal. -- http://mail.python.org/mailman/listinfo/python-list
