Look for help on -in- and -egen, seq()-.

Or to put it another way:
How can I tag specific observations (let�s say obs 1 to 100,000) and define their outcomes in variable x?

I need to create a reference dataset for weighting. I stratified my dataset into 16 cells. The reference dataset describes the city of Leipzig for sex, age and (un)employment. I stratified these informations likewise and hoped to finally crate a dataset with 504.000 observations and one variable, containing 16 categories. So I could calculate the needed weights to adjust my original sample to the population of Leipzig.

BUT, how to I define which observation belongs to which cell?

I started this way:

set obs 504000
generate cell = 0

Well, and now? I thought about the replace command

replace cell = 1 [ and here should be said which obs belong there!]
