See page 8 of the documentation for the display. There's a control code that you send to the display to turn the backlight on and off. This assumes that you have one of Parallax's backlit displays.

To display a number, since you're using the SEROUT statement to send characters to the display, you use the DEC formatter to convert the number to a series of digits for display. Read the Stamp Manual chapter or Stamp Editor help files on the SEROUT statement. Also, Appendix C has some additional material on the different formatters.

If you look at the webstore webpage for any Parallax product, you will usually see links to documentation, sample programs, demonstration videos, etc. For example, see here (http://www.parallax.com/Store/Accessories/Displays/tabid/159/CategoryID/34/List/0/SortField/0/Level/a/ProductID/50/Default.aspx). If you go to the main Parallax webpage, you'll see a button labelled Downloads. Click on that and you'll find a webpage with links for a variety of documentation. The button labelled Stamp Documentation has links to manuals like the Basic Stamp Syntax and Reference Manual. On the same main webpage, there's a tab labelled Resources. There you'll find a link to the index for the Nuts and Volts Columns which are also full of project descriptions, sample code, schematics, explanations, etc.
