Sorry, poor wording. I was relying too much on context. I use wildcard varlists all the time; I've just never wanted to use them within

For example, suppose you wanted to do something with all system-generated variables _*, knowing that these might be scattered around the dataset and not contiguous.  How would you do that without wildcards?
