I guess everything hinges on the precise meaning of "rather long".
I'd start by studying Kit Baum's FAQ
FAQ . . . . . . . . . . . Defining group characteristics to create subsets

in your data in order to create subsets?

I have a rather long list of five digit alpha-numeric codes (eg W41.3,
W91.8, W98.7...).
How do I keep those records where at least one of twelve variables (eg
opcs1, opcs2,..., opcs12) contains at least one of the aforementioned
alpha-numeric codes?
