You are right in thinking that I am concerned with global variables. I don't have a problem with using global variables for things that genuinely are global. Typically I read or generate these at the start of my code and then never change them, so I'm not particularly concerned for my sanity in that regard. I intended my OP question to be along the lines of "how do I avoid typos creating global variables I didn't want". If I can't do that, I have genuine fears for my sanity. :-)

Regards,

John Davies
