Welcome to the ugBASIC sandbox!

This tool was 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 executables or the UGBASIC-IDE.
