Subject:      Problems selecting a random sample of cases
Content-Type: text/plain; charset=US-ASCII

I'm trying to debug some syntax.  Rather than use the full data set of more than 300,000 records, I want to select a random sample of 6% of the data (first saving the original file under a new name) and delete the unselected cases.

I used the point-click-paste method to generate the syntax below:


FILTER OFF.
USE ALL.
SAMPLE .06.
EXECUTE .


When I run it, I don't get any error messages but I still have all 337,000 cases.  Can anyone tell me what I'm doing wrong?

I'm using 11.5.

TIA

Pat
