local ds1 "D:\_Dummy\multiple\1\auto_1.dta"
local ds2 "D:\_Dummy\multiple\2\auto_2.dta"
local ds3 "D:\_Dummy\multiple\3\auto_3.dta"
local all ds1 ds2 ds3
local y = 1999
foreach x in `all'{
use ``x'',clear
include "D:\_Dummy\multiple\4\"
include "D:\_Dummy\multiple\5\"
local ++y
gen year = "`y' "
save ``x''_new.dta,replace

local ++y

could be

local y = `y' + 1

The whole thing could be shorter.
