All the data quality flag variables (all of which I believe begin with a “Q”) are missing from your alphabetic variable name list. Could someone fix this? I reported it back in July.
If you don’t intend to fix it, the dropdown list should have its name changed to “A-Z except data quality flag variables,” and the dropdown selection that currently just reads as “Q” should be renamed to “Q except data quality flags.” Otherwise they are misleading.
