st: Svy subsamples

[Richard Williams <Richard.A.Williams.5@ND.edu>]

I know that when using the svy: prefix, you should use the subpop 
option when analyzing subsamples, rather than using if or dropping 
cases.  However, I have a student who has this monstrous data set and 
she only wants to analyze a small subset of it.  I'm afraid that if 
she has to keep all these unused cases in her file, her 
not-so-powerful computer is going to have problems.

Is there a legit way to extract only the cases you want?  Is it all 
that horrible if you extract cases rather than use subpop?

Thanks for any info.  And Happy Thanksgiving to all those who celebrate it.
