Abstract. A standard task in data management is producing a list of variable
names showing which variables have specific properties, such as being of string
type, or having value labels attached, or having a date format. A first-principles
strategy is to loop over variables, checking one by one which have the property or
properties concerned. I discuss this strategy in detail with a variety of examples.
A canned alternative is offered by the official command ds or by a new command,
findname, published formally with this column.
