Filtering a specific sample of cases (not random)

I recently started using PSPP to analyse sav data. I must say that I
have no previous experience with SPSS. But from what I have seen so
far, I very much like PSPP. I have one (maybe simple) question that
I couldn't find an answer for in the documentation.
In an Excel file I have a list that looks as follows:
Cluster | Code
2A | 33edfdkeew
2A | 29dnewdnd
2B | sd2034wss
2B | 29jsnn2221
Then I have a sav file that I analyse with PSPP. This file contains
~ 400 cases, all with unique entries for the "Code" variable. I want
to perform the analysis of the data for the different clusters.
Thus, I want to filter the file for cases whose codes belong to a
What is the best way of doing this in PSPP?
Select cases only allows me to select a random case sample, based on
a range (but only allowing me to select case numbers) or a filter
variable (which I don't have in my default sav file).
My current idea was to create 2 new variables for the two different
clusters and then assign a 1 to the variable for each case that
belongs to the respective cluster. However, this seems to be very
inconvenient and I am wondering if there is a better way to do this.
