That's right, there are quite a few of these, and some of them are quite long.

Yes. I'm new to SAS, having used SPSS before. The autorecode command
(in SPSS) puts the values into alphabetical order, and creates a new
variable, where the first becomes 1, the second becomes 2, etc.

I wanted to write some code to place these into groups, so 1, 2, 3, 6,
7 and 9 (for e.g.) would become 1, and 8, 13, 14, etc, would become 2.
I could then write
if code = 1 or code = 2 or ... then censored = 1;
Without having to write each string out in full (and risk making mistakes).
