I have created an observation variable X (e.g. gen X=_n) for a large data set. How can I create a new variable that is unique for successive observations of 10 variables (i.e. i want this variable to be equal to 1 in obs 1-10, 2 in 11-20, and so forth)?

Try this:
clear
set obs 50
gen X=_n
gen X1 = int((X+9.5)/10)
list
I added 9.5, not 9, to prevent rounding errors.
Hope this helps.
