Hi,

I have data in the wide format with the id in the first column, then in the
following columns the data on the return index I use, as it is monthly data
I have 12 columns for each year (i.e. the first row reads: id, 31.1.1990,
30.2.1990, 31.03.1990 and so on).

It works out great if I use 

reshape long ri, i(id) j(newdate)

when I have only years, but I can't figure out how to get it to work with
the dates. (After reshaping I would like to have a month variable and a year
Variable out of the date part, so I have monthly data.)

thanks for your suggestions
-Tom
