You don't. If you need one of the functions or commands that have a "%" in the name, you'll have to access it from the catalog or a menu. You can't put the percent symbol into a prompt or text string.

The Transfrm application has been executed previously. It remains in RAM and takes over the graphing duties of the native OS. You must Uninstall Transfrm (that does not mean delete it, just unload it from memory).
To do so,

1. press the [APPS] button.
   
2. Use arrow Up or Down (Up is faster) to reach Transfm.
   
3. Select it and press [ENTER].
4. In the new screen, select the number to the left of the Uninstall option.
5. Go to draw your graphs. You will be able to draw up to 10 graphs.
