Jose,
How would you collect back the date values if you needed them as well
as the price (or whatever array was desired) on the given date input?
Can one collect params from the formula? Can they be coerced into the
nasty YYMMDD format?
In other words I enter the date I want, say 2004, 03 (March), 24
(day). Can the legit start date then be returned since the date
entered might not be precisely the one used? [e.g the user enters a
non-trading day for which there is no data].
I happen to be using an older, persnicked .dll that doesn't like
variables (solved by lastValue) but expects the date back in this format.
PS. Where can one buy one's very own Jose de Silva?
