Have you had a look at -help whatsnew9to10-, particularly "What's new in
data management"? And try both versions of this:


*************
di date("102108", "mdy", 2010)
di date("102108", "MDY", 2010)
*************

Betreff: st: -date- creates missing values

Hello friends,
I recently moved a do-file from Stata 9 to 10, and the following short  
date program, instead of creating Stata dates, now creates missing  
values. It's supposed to take dates in MM/DD/YY format imported from  
an Excel .csv file, and translating them to Stata date format.

I'd appreciate any pointers/critiques on my method, or what I missed  
in the 9 to 10 upgrade...

*prep date vars, from mm/dd/yy
    foreach D of varlist d_sample1  ///
                         d_sample2 ///
                           {
      generate `D'1 = date(`D', "mdy", 2010)
      format `D'1 %d
      drop `D'
      rename `D'1 `D'
     }
