Generating a performance summary at task completion?

[David McFarlane]

Morgan,

By now you no doubt have this sorted out, but for the record I just 
want to mention that you might be able to use global Summation 
Objects instead of a bunch of separate variables to keep track of all 
your statistics for a later summary.  Please see the Summation Object 
topic in the online E-Basic Help.  You would still need script 
similar to what liwenna has shown in order to update the Summation 
Objects and to manage the final summary slide.
