De Re BASIC!
Menus
Press the MENU key or touch the Menu icon to access the following menus. On some versions of
Android, you will not see all of the menu options. Instead, you will see the first five options and a More
options. Select the More option to see all of the options listed.
Run
Run the current program.
If the program has been changed since it was last saved, you will be given an opportunity to save the
program before the run is started.
If a run-time error occurs then the offending line will be shown as selected in the editor.
Load
Load a program file into the editor. The first time you open BASIC! after installing it, if you select Load it
displays the sample programs in the directory rfo-basic/source/Sample_Programs. (See Paths
Explained, later in this manual.) Otherwise, when you open BASIC! and select Load it starts in the
default source directory rfo-basic/source. Program files must have the extension .bas.
BASIC! checks to see if the current program in the Editor has been changed when Load is tapped. You
will be offered the opportunity to save the program if it has been changed. If you choose to save the
program, Load will restart after the save is done.
The "BASIC! Load File" screen shows the path to your current directory followed by sorted lists of the
subdirectories and program files in it. Directories are denoted by the (d) appended to the name. BASIC!
programs are shown with the .bas extension. If there are files in the directory that do not have the .bas
extension, they do not appear in the list.
Tap on a .bas file to load it into the Editor.
You can navigate to any directory on your device for which you have read permission.
Tap on a directory to display its contents.
Tap on the ".." at the top of list to move up one directory level. The tap has no effect if the
current directory is the device root directory "/".
You can exit the Load option without loading a program by tapping the BACK key.
BASIC! remembers the path to the directory you are in when you load a program. Next time you select
Load, it starts in that directory. If you select Save or Save and Run, the file is saved in the remembered
directory (unless it is Sample_Programs).
Save
Saves the program currently in the editor.
