wrapping up using lines of codes in a loop

[Nader Mehri]

Hi,
How can I wrap up the below code in a loop?
Best,
Nader

gen n=_n
gen sample=_n
replace sample=1 if n<=1000
replace sample=2 if n>1000 & n<=2000
replace sample=3 if n>2000 & n<=3000
replace sample=4 if n>3000 & n<=4000
replace sample=5 if n>4000 & n<=5000
replace sample=6 if n>5000 & n<=6000
replace sample=7 if n>6000 & n<=7000
replace sample=8 if n>7000 & n<=8000
replace sample=9 if n>8000 & n<=9000
.
.
.
replace sample=65 if n>64000 & n<=65000

No loop needed, just mathematics.

. set obs 65000
number of observations (_N) was 0, now 65,000

. generate n = _n

. generate sample = floor((n-1)/1000)+1

. tabstat n, statistics(min max) by(sample) nototal

Summary for variables: n
     by categories of: sample 

  sample |       min       max
---------+--------------------
       1 |         1      1000
       2 |      1001      2000
       3 |      2001      3000
       4 |      3001      4000
       5 |      4001      5000
       6 |      5001      6000
       7 |      6001      7000
       8 |      7001      8000
       9 |      8001      9000
       .
       .
       .
      65 |     64001     65000

William Lisowski is right. Here is another way to do it without a loop, assuming his framework.

generate sample = ceil(_n/1000)
