Essentially yes.

I'm sure it isn't.

I accept that but I *imagined* that when you run a basic program the
OS would somewhere store the path to the running file.  

There is I do know, a start string which can be intercepted through
vector 5 and that does contain the full path to the file name. I
already harvest that to get my system variable Basic$Dir useful for
saving data or code in the same directory.

Getting the file name seems a bit harder but not sure why yet.

All the above is fab except the word "manually*.

Cheers,
