Subject: st: Verify that all values of a variable are mapped after -label values-

What is the easiest way to check whether, having applied a value label to a variable...

  label values myvar mylabel

...every value of myvar in the dataset is mapped to mylabel?

I am using Stata 10, creating value labels from lookup files from numeric code variables to string descriptor variables using -labmask- followed by -label save-, and then applying them to the values of the numeric variables in very large datasets.

The obvious solution might be to merge the string variable itself from the lookup file into the target file (after which I could check the integrity of the merge, use -labmask-, and drop the string variable again) because I want to avoid that because of file size and read time  considerations.

Thanks in advance to anyone who knows the answer offhand!

Toby
