As requested by a user, I've added the possibility to pass arguments to a running script. The arguments are passed as a string (named _Args). The new version is available from the usual place.
One thing I have noticed is that scripts that contain encoding information give a run-time error. It is thus necessary to remove the encoding information (a line like # -*- encoding: latin-1 -*-) prior to running the script. If anyone knows of a different workaround, I'd appreciate hearing about it.
