No, it looks like a bug to me. It occurs when the code
tries to tokenize the category label, parsing on "==".
Apparently Stata treats the == as a parse character
(note singular) being accidentally entered twice, therefore
setting parse() equal to "=". Just as Stata would ignore
multiple spaces in a row, or a comma-space combination, it
freely parses =, ==, or ===, etc. as a single token split.
We see in the code:
- tokenize "`vlbl`i''", parse("==")
= tokenize "bearings==abnormal=no", parse("==")
- cap confirm number `3'
= cap confirm number abnormal
The third token is "abnormal" rather than "abnormal=no".
