Probably. But I'm this close to getting it in DTML, so I'll finish up with 
that, then look at a Python script.

I've done as you've suggested. I may not use this, but I'd like to gain 
some understanding in my continual struggle to advance, nanometer by

That is just the part I wanted. I'm still a little foggy on this *context* 
stuff.
