" Obviously I open the data editor and input the values by manually"


In the absence of evidence to the contrary, we have to assume that you are a
Stata 11 user, so if you did enter some values into the Data Editor, the
commands executed would be echoed to Stata`s Results window, and this would
give you a hint as to the -set obs- that Eric pointed out to you. Output for
inputting the numbers 1 to 6 is:

***
set obs 1
generate var1 = 1 in 1
set obs 2
replace var1 = 2 in 2
set obs 3
replace var1 = 3 in 3
set obs 4
replace var1 = 4 in 4
set obs 5
replace var1 = 5 in 5
set obs 6
replace var1 = 6 in 6
***

from scratch ?

Hello,
I would like to create a completely new dataset from scratch with just
one variable. I would like the variable (age) to have 80 observations,
increasing sequentially.

Example:

age
1
2
3
4
..
80


I have tried a few different things, eg

clear
gen age=_n

or ...

clear
gen age=1
replace age=_n
keep if age<=80


but nothing happens....

Does anyone know how to do this. I have tried searching for
information but it is one of those things which is hard to search for.
Obviously I open the data editor and input the values by manually but
I would prefer to have something reproducible.

Thanks!
Anna
