Re: today's how-best-to question...

Question for you: How would you envision a user using a 9,999 line 
subfile?  That is something on the order of 500 page-ups & page-downs.  
If you add a scroll bar they can easily zip through the subfile but its 
almost impossible to stop the scrolling on the page the user wants.

My answer to your question is to ask that you consider some sort of 
process that will divide your listing in some arbitrary way and keep the 
list at 2500 or so records.

Also, use the scroll bar!  It really helps the paging problem when there 
are lots of pages and its only one word of coding, although it does use 
3 columns of real estate.

(Here is a screen shot that shows what the scroll bar looks like.
