Hello World

FreeBASIC

Hello World
 
This example is a classic in any programming language.

More as a sanity check than anything else, a good place to start with any programming language is to try a very simple program to test that the compiler is installed correctly and that a valid executable can be made.

Open up any editor capable of saving text files and type in the following source code:
Print "Hello World"

Save the file with a '.bas' extension. For example 'hello.bas'

From a command prompt or shell in the directory where 'hello.bas' was saved, type the following command:
fbc hello.bas
Depending on the operating system, this should create an executable file in the same directory as 'hello.bas'. It might be named 'hello.exe' or './hello', for example.

Run the executable, and we should have the following output:
Hello World
