Using the True BASIC 6.0 Editor Even if you are familiar with word or text processors you are still advised to read these notes because the new True BASIC editor contains a number of unique features that are not available in previous TB editors or other text editors. START UP When you start True BASIC for the first time the screen will show an empty window labelled “Untitled 1” in the top left corner of the screen. In earlier versions at start up, True BASIC displayed a small file selector dialog box where you can click on the NEW button to start with an empty, untitled window. i There are several ways of starting the editor: (1) Double click on the editor desk top icon. (2) Set up a file association between TRU files and the editor. (3) Drag file icons onto the editor icon (4) Chain to the editor from another application File associations can be set up from Windows control panel: Select Folder Options. Click the File types tab. Scroll down the list of extensions and click TRU Click the CHANGE button. Click the BROWSE button and then navigate to TBeditor.exe in the folder where you installed the editor. DEFAULT SETTINGS (settings menu) The following settings have been pre-set, but you can customize them at any time. Any change in settings will remain in force until you next change them.
