Woops, my code below doesn't bother to save the dataset...
the following 2 lines should be changed:

if `x'==1910 & `i'==1 save mysample
else append using mysample
should be

if !(`x'==1910 & `i'==1) append using mysample
save mysample, replace

Why not just create one big dataset and then pull it apart at the end:

forval x =1910/2000 {
local i=1
while `i' <=10 {
use `x'

sample 5, count
gen dataset=`x'
gen samplenum=`i'
if `x'==1910 & `i'==1 save mysample
else append using mysample

* delete this line> save sample`x'`i', replace
local i= `i' +1
}
}
* now you have mysample with vars dataset, samplenum, and the variable of interest. You could save pieces however you want using another loop...
