{{fbdoc item="title" value="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:
{{fbdoc item="filename" value="examples/manual/proguide/helloworld.bas"}}%%(freebasic)
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
%%
