date
if you can get your starting date as a Stata date (perhaps input month day
and year as 3 arguments) you can then generate the required formatted date
strings like this:
args m d y
local dateanchor=mdy(`m',`d',`y')
forval i=1(1)39 {
local thisweek: di %dNDy (`dateanchor'-7*`i')
insheet using Q:\DS5\BILL.WE`thisweek'.csv, comma clear
etc...
}
The key to this code is using Stata's date formatting and the -local : di-
construct.
