You need to specify the file that fpc.exe needs to convert.

If you have a file called, for example, 'hello.pas' that looks like this:

program hello;

begin
   Writeln('Hello, world!');
end.

then the command

fpc hello.pas

will convert it to an executable.

If you don't give any options to fpc, it will display the help, and asks
you to press enter, this is what you have observed.
