Just an FYI, in general, if you'd like your files to be named explicitly, surround them in double quotes. On Windows, in Notepad (for example), saving a file by just providing a name, my_script, will save the file with an *actual* name of 'my_script.txt'. To have it named 'my_script.pl', tell the save dialog the full name and surround it in quotes: "my_script.pl". The application will then _not_ add its default extension.
