*Assign numerical codes
loc idk     -99 99 999  // numerical code for "Don't Know"
loc rf      -77 77 75   // numerical code for "Refuse"
loc na      -88         // numerical code for "Not Applicable"
loc oth     -66         // numerical code for "Other"
loc skip    -70         // numerical code for  "Skip"

where loc for local is not in line with community guidelines

Good suggestion. We should avoid using concatenated Stata commands since this will be hard for new Stata users to understand and there's lots of room for variance in how Stata commands get shortened.
