You can use the SANDBOX to try the ugBASIC compiler, without download anything. This tool has been designed to quickly test whether the code you are writing compiles correctly and determines the desired results.

Since the source is compiled thanks to dedicated servers, separate from the browser you are using, some commands are not available: for example, you cannot load external files or resources by using the LOAD command.

If you need to develop a program with a complete tool, we recommend installing the command line executables (see below) or UGBASIC-IDE.

To write the source code you can use a simply text editor. You can save the program in a text file and then to call the compiler, in order to convert it into an form that your Olivetti Prodest PC128 and Thomson MO6 will be able to execute.

Otherwise you can download and use command line compilers. Here are the direct links to the compilers for the various operating systems. Select the most suitable one for your configuration:

• Linux (32 bit)
• Linux (64 bit)
• Windows (32 bit)
• Windows (64 bit)
• Microsoft Windows IDE (32 and 64 bit)

In addition to compiling with the IDE, if you are using Linux or the command line version for Microsoft Windows, you can compile the BASIC source "source.bas" into an executable file using the following command:

ugbc.pc128op -o executable.k7 -O k7 source.bas
ugbc.pc128op -o executable.bin -O bin source.bas

It is therefore possible to run everything with an emulator, such as DCMOTO using the following command:

CLEAR,&H2FFF:LOADM"",,R

or to create a phisical storage, as well.

A good starting point to learn ugBASIC for the pc128op platform is the examples page. The examples provide insight into the syntax and usage of many of the commands and statements available for the language.

Since ugBASIC is an isomorphic language, which does not provide abstractions, it is possible that not all examples work on all targets: those labeled pc128op can be compiled to generate executable files.

If you need help and support, the best place is the official forum, where you can find answers to your questions and receive help.

VIDEOGAME ISPIRED

The ugBASIC compiler supports both the Olivetti Prodest PC128 / Thomson MO6 PAL (working frequency: 50 Hz) and NTSC (working frequency: 60 Hz) versions, and automatically detects the working frequency to calibrate the delays. In particular, it defines two constants with the same name, and initializes the constant TICKS PER SECOND.

This is the value of the various constants in the various versions:

The ugBASIC language supports only the keyboard.
