You can peel this off one by one using -separate- with an expression:
*************
clear*
inp str9 todate1
"30-Jun-99"
"10/15/99"
"4/15/1998"
"4/15/1998"
"8/15/1998"
"3/15/00"
"6/1/1998"
"6/1/1998"
"1-MAR-00"
"1-MAR-00"
"1-MAR-00"
"1-MAR-00"
"02/15/98"
"12/01/98"
"1-AUG-00"
"8/15/1998"
"8/15/1998"
"6/30/1998"
"6/30/1998"
"7/1/1999"
end
gen mydate=date(todate1, "MD20Y")
//weed out the ones still missing
separate todate1, by(mi(mydate))
list, noo
*************
Then it is on to the next set of problematic dates...

Betreff: st: converting varying formats of string dates into Stata dates
Greetings Statalist:
First, I hope my attempts at removing the HTML text were successful. If
not, apologies in advance.
Second I have several fields that have dates in all sorts of manner, for
example (and there are more types, like mar-01-2000, this is just a
smattering):
. l2 todate1 in 1/20
+-----------+
| todate1 |
|-----------|
| 30-Jun-99 |
| 10/15/99 |
| 4/15/1998 |
| 4/15/1998 |
| 8/15/1998 |
|-----------|
| 3/15/00 |
| 6/1/1998 |
| 6/1/1998 |
| 1-MAR-00 |
| 1-MAR-00 |
|-----------|
| 1-MAR-00 |
| 1-MAR-00 |
| 02/15/98 |
| 12/01/98 |
| 1-AUG-00 |
|-----------|
| 8/15/1998 |
| 8/15/1998 |
| 6/30/1998 |
| 6/30/1998 |
| 7/1/1999 |
+-----------+
Is there an ado-file or function out there that can help fix this? We have
something called chgdate, but it assumes that all the variables are in
"xx/xx/xxxx" format and drops everything else. My goal is to have 1
variable that has a date in the Stata date format.
Thank you!
