For-loop and ActiveRowCount

I'm using a For-loop and ActiveRowCount to loop through what I thought were all the rows on a scroll.
 
There are 700  rows in my Level-0 scroll.  The page displays only 100-rows at a time in level 1 (the default setting).  In this scenario, the PeopleCode Command Processor thinks ActiveRowCount = 100 (since that's all that are visible on the page). 
 

QUESTION:  Is there a better way to loop through ALL rows in a scroll even if not ALL rows are being displayed on the page?  TotalCount gives same results.
 
NOTE: none of the rows have been marked for deletion.  PeopleTools release 8.51.
