I misunderstand something about the way locals are identified. The below program crashes when I try to -use- the filename in `r(files)'. If I take out the path name and change into that directory, then the program runs. How can I make this work with the path name? What is the proper way to use a local that is appended to another string, such as the path? Thanks!

. fs c:\union_pop\orig\gifford*.dta
gifford_2000.dta

. foreach file in `r(files)'{
2. use "c:\union_pop\orig\""`file'", clear
3. ds _*
4. foreach var of varlist `r(varlist)'{
5. bysort id: assert `var'==. if `var'[_n+1]!=.
6. }
7. }
invalid '"gifford_2000.dta'
r(198);

end of do-file

r(198);
