st: using information in value labels

["Alexander Nervedi" <alexnerdy@hotmail.com>]

Hi

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.

Saludos!
Alex
