The following diagram shows a simple SurferScript section which enhances a screen which displays the active interest rates for a fictitious bank.

Note that not much has been done to reformat the dislay, while attention has been paid to the layout and providing buttons for the enter key and PFKeys.
For more information on implementing your own Surferscript sections, see the DevCenter Introduction Section, and the following sections, which describe Surferscript in more detail.
