Hello Grant,

I'm pleased that I could help you. What I forgot to tell you: When you insert a
new camera, you have increase the number at the beginning of the file by 1.

@ Bill: Perhaps it is favourable to reserve an ID block of perhaps 5 or 10
numbers for such a personal use so that they aren't overwritten or used twice
during the next update of cameras.
