You can download the official ugBASIC compiler (ugbc), which directly converts a program written in ugBASIC into the assembly equivalent for the given CPU / computer. The compiler is free, open source and licensed under the Apache 2.0 license. You can download or recompile the latest version from the GitHub repository.
At the moment there are two manuals available: the user manual, with which you can start developing using this language, and the reference manual, useful for those wishing to modify and/or to extend the language.
