Dear all,

I am trying to transfer some results into a new dataset using -postfile- but I am not sure I am doing it in a very efficient way.

Although the code is running fine with the example dataset, I am sure it could be improved (and maybe avoid potential problems that I haven't even thought of).

Could anybody please offer any advice?

Thank you in advance
Manos


******************* Example code ******************
webuse intregxmpl, clear

intreg wage1 wage2
predict pr, pr(wage1, wage2)
egen rm=rowmean(wage1 wage2) if e(sample)

tempname A B
tempfile gr1 gr2 graphs

postfile `A' str8 pr using `gr1', replace
levelsof pr
local lev "`r(levels)'"
foreach i of local lev {
        post `A' ("`i'")
}
postclose `A'

postfile `B' str8 rm using `gr2', replace
levelsof rm
local lev "`r(levels)'"
foreach i of local lev {
        post `B' ("`i'")
}
postclose `B'

use `gr1', clear
destring, replace
gen n=_n
sort n
save , replace
use `gr2', clear
destring, replace
gen n=_n
sort n
save , replace

use `gr1', clear
merge n using `gr2'
drop _merge
save `graphs', replace
