Bruce:Thanks for that instant reply. I must admit that as soon as I hit "send" on my enquiry, my brain thought "wait a minute -- environment variables?!" and I was just trying that out.
Of course, I would never have found the tksurfer-defined ones, so that's a great help. Probably the rest of the bunch would be useful too....
