Matthew,
Although I'm sure you can work the problem with the data in a 'long' format,
I'd convert it to 'wide' via a Casestovars command (I'll assume you are
familiar with this command from the syntax reference.) Then,
Do a count of sysmis/missing values for the six husband/wife T1-T3
variables.
Get rid of cases with a count of 1 or greater.
Run a frequencies to get the number of valid cases. Let this number be M.
Do a sample command of this form (refer to syntax reference for
documentation):
Sample 200 from M.
Finish up with a Varstocases command to restore your data to the prior long
format.
