Yep - cur = nil is what you'll want to destroy cursors that are not dimmed
local to a method.

I use doubles instead of dates in V4RB... For base object, I'd use:

d = new date
d.totalseconds = data.MyDateDouble.value

It's really much better to use cursors:

d.totalseconds = cursor.doublefield("MyDate").value
cursor.add   //or cursor.update

Correct. GetString is simply doing the string conversion for you. I use this
all the time for listbox population. It's pretty fast in my tests.

HTH,
