[Zope] How do you call a shell command from an external method

I have been trying to get Ploticus to work from an external method with no luck. I put the file (pl.exe) in the Extensions directory for the quick test and used the following code" import os def test(self): result = os.system("c:\\Progra~1\\WebSite\\Extensions\\pl gantt.pl -gif -o test.gif") return result If I run the command from the prompt it works great. When I call this function from Zope I get a return value of 1 and no file is created. I have tried numerous variations on the path with no luck. Does anyone know how I can shell out to the program?
