Choose to allow the Sensors to determine the orientation of the screens or to set a fixed orientation
without regard to the Sensors.
Note: The reverse orientations apply to Android 2.3 or newer.

CCELERATION
Check this box to enable GPU-assisted graphics acceleration on devices since 3.0 (Honeycomb) that
support it. It is disabled by default. If you enable this option, test your program carefully. Hardware
acceleration can make some of BASIC!'s graphical operations fail.

Some Android devices have several external storage devices (and some have no physical external
storage devices). BASIC! will use the system-suggested device as its base drive. The base drive is the
device where the BASIC! "rfo-basic" directory (base directory) is located. The base directory is where
BASIC!'s programs and data are stored. (See "Working with Files", later in this manual.)
If your device does have more than one external storage device they will be listed here. If your device
has no external storage devices, your one and only choice will be "No external storage". Tap the device
you want to use as the base drive and press the BACK key. You will then be given the choice of either
immediately restarting BASIC! with the new base drive or waiting and doing the restart yourself.
In this manual, <pref base drive> means the base drive you selected when you set the Base Drive here.
Note: If you have created a Launcher Shortcut (see Appendix C) with files in one base directory but try to
execute that shortcut while using a different base directory, the shortcut will fail to execute.
Commands
The Commands command presents the list of the BASIC! commands and functions as copied from
Appendix A of this document.
Tapping an alpha key will cause the command list to scroll to commands that start with that character.
There will be no scrolling if there is no command that starts with that character.
Note: You can hide the virtual keyboard with the BACK key. If you do that, you will not be able to get it
back until you invoke the Commands option again.
Tapping on a particular command causes that command to be copied to the clipboard (not including the
page number) and returning to the Editor. You can then paste the command into your BASIC! program.
About
The About option displays the version of BASIC! that you are using, followed by a set of buttons that
connect you to various websites with information about BASIC!. Make sure that you have a connection
to the Internet before selecting one of the About buttons.
