2. Tap the Tran button on the Toolbar or use the command on
the Tools menu to translate the file into a program you can
run on the netBook.
If an error is found during translation, the cursor is positioned at
the point in the program where the error is found and an error
message is displayed. Refer to the OPL Programming Manual for
details of error messages.
3. Once the program has been translated without errors, you
can run it.
The translated (executable) file will be given the same filename as
the source file, but with the extension .OPO. To run the program
from the System screen, highlight it and then tap on it, or press
Enter.

Three languages are provided to allow you to program your
netBook - OPL, C++, and Java.
• OPL is a BASIC-type language which can be edited and
translated on the netBook. For more details on OPL, please
refer to the “OPL programming manual” on the CD, or
download the OPL32 SDK from the EPOCWorld website,
www.epocworld.com.
• C++ is the native language of the netBook, and allows the
greatest access to operating system services. It is necessary
to compile C++ programs on a PC - there is a Windows
netBook emulator to allow development and debugging to
take place on a single machine. The netBook C++ SDK
may be downloaded from the EPOCWorld website,
www.epocworld.com.
• Java is a platform-independent language developed by Sun
Microsystems Inc. Programs written using Java technology
may be run on a variety of computing platforms which have
a Java Virtual Machine (JVM). The netBook Java SDK
(including the netBook JVM) can be downloaded from the
EPOCWorld website, www.epocworld.com.
