I would like to control the amount of data displayed on a page, anyway how?

I made a query to the DB for 400 items

and would like to only display 50 at a time.

Thanks!

in a printed report, i believe $= is the page length parameter. In your code, just set it to something other than the default:

Some experimentation is likely to be necessary to account for headers, footers, and other oddities.
