Hi Hailing
My reading into your question, you have a string variable var1 in this
format
var1
08/01/2001 --Wed
08/02/2001 --Thu
08/03/2001 --Fri
08/05/2001 --Mon
and you would like to extract the first part which is the date. To do this,
you can use
gen str18 bdate = substr(var1, 1, 10)
compress
This should help you extract the first part from your variable into a new
variable bdate. That having been said, you might wanna consider formating
the new variable using statas date functions.

Subject: st: How to insert new observation?
Hi,
I am trying to insert new observations into the existing data file. For
example, the trading days are only weekdays, namely Monday through Friday.
But I also wish to list Sat and Sun in the data file. (So only date appears,
other columns will be blank because of no data.)
for example:
08/01/2001 --Wed
08/02/2001 --Thu
08/03/2001 --Fri
08/05/2001 --Mon
I wish to have 08/04/2001 and 08/05/2001 appears to be able to merge with
other data sets. How can I do that?
Thanks a lot!
Hailing
