DB2 V7 z/OS Unload utility and when-clause

Hi

I want to do an unload of a big partitioned tablespace, but I only want to
unload parts of it, say rows of partition n and n+1, but I do not want to
unload all rows from both parts. So I code the when-clause accordingly by specifying the leading columns of the partitioning index. Now my question: Does the unload do something like a page range scan or does it do a full tablespace scan?
