I have a column containing the days of the year and all I want to do is run a code to pick out 10% of them at random and populate another column (or sheet). I believe the below code would work but I don't even know where to put it or how to run it. If there is an easier way of doing this please someone let me know. Please help me, I know it's probably an easy thing to do. Thanks

Code:
GET
     FILE='C:\whatever.xls'.
FILTER OFF.
USE ALL.
SAMPLE 37 FROM 365.
EXECUTE.
