st: How to insert new observation?

["Zang Hailing" <hailing-zang@neo.tamu.edu>]

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
