My guess is that in simplifying the snippet you gave us, we've lost some information about why you couldn't just separate these two processes ( that is, (1)creating the 100 observation dataset with random "x" and (2) inputing a dataset with a variable "lines") into different loops -- they don't seem to inform one another in any way.
I'm not sure why the input - end causes a loop to break (might have something to do with input being an interactive command ?), but could you replace it with -gen- and -replace- commands ? e.g.,
******
local i 1
while `i'<=10 {
clear
set obs 100
gen x=uniform()
sum x
clear
set obs 2
g lines = "rec" in 1
replace lines = "dat" in 2
save temp`i', replace
local i=`i'+1
}
******
