st: using information in value labels

I have a complex survey dataset which has been helpfully cleaned - each variable has its missing values coded with 9/99/999/999 or 98/998/9998 etc. and things like Missing, Did not respond, refused to answer etc. are all coded in as value labels.

I would like to treat all of these as missing and want to run a loop as follow

local allvars x1 ... x100

foreach var of local allvars{

label list `var'
*pseudo code follows
scan label to see which levels include - "Missing", "missing", "did not respond", etc
for each level `i' {
recode `var' (`i' = .)


I was wondering if this is something that could be reasonably be implemented.
