program then loops over these dates performing a function.  I'd like to loop
until I hit the last date in my dataset which will change each time I run the
program depending on the size of the dataset.  Can someone please recommend an
efficient way to identify my last column so I can define NumDays?

local NumDays = ?
local i = 1
while `i' <= NumDays {
    ...
}

cheers!
