"Is there any way I can change tradedate into Stata date format without

Even if you disregarded Michael`s advice and wanted to stick to your
splitting strategy, there is no need for external software:
***********

inp str8 tradedate
20010102
20010103
20010104
20010105
20010106
20010107
end
gen day=substr(tradedate,-2,.)
gen month=substr(tradedate,5,2)
gen year=substr(tradedate,1,4)
destring day month year, replace
gen date=mdy(month,day,year)
format date %td

Dear Statalisters,
I imported daily stock data from CRSP. The data shows date like this:
tradedate
20010102
20010103
20010104
20010105
20010106
20010107
......
Neither of the following commands works:
- format tradedate %td
- gen date=date(tradedate, "MDY")
I split tradedae into month, day, year in excel, imported into Stata, and
used the following command to combine them.
- gen date=mdy(month,day,year)
Is there any way I can change tradedate into Stata date format without using
excel?
Thank you in advance,
Mike.
