If you wind up with logical==0 everywhere, you might have included a
string variable in your varlist... try also

gen byte allmiss = 1
ds a10*
foreach v in `r(varlist)' {
qui replace allmiss = 0 if !mi(`v' )
}
list if allmiss==1

but are you sure you want to list all variables in all observations
where all a10* are missing?  You will be listing a lot of dots...
maybe you want to

gen byte allmiss = 1
qui ds
local allvars `r(varlist)'
qui ds a10*
local avars `r(varlist)'
local tolist: list allvars - avars
foreach v of local avars {
qui replace allmiss = 0 if !mi(`v' )
}
list `tolist' if allmiss==1
