I've never used -findname- before, but you've maybe made a mistake by
using the same name for the local macro in your loop as you did for
the one you are storing the variables that match in your call to
-findname-. Try the following...
findname, all(@==1|@==.) local(varname) varwidth(30)
di "`varname'" // Check that there are some variables that match
your criteria!
foreach x of varlist `varname' {
replace `x'=0 if `x'==.
}
