Hi Jure,

I was hoping to get some feedback (which has happened, thanks all) before 
trying anything, including that and other error traps / crosschecks, given 
the fact that I only delve back into my programs on rare occasions, and so I 
might know what to look out for when I do them. I will do this and report 
back soon. Thanks.

Phil
