Here is the “Hello World!” program written in Pascal:
program HelloWorld;
begin
writeln('Hello, World!');
end.
Let me explain what’s going on here:
programis a keyword that declares a new program. The name of the program isHelloWorld.writelnis a procedure that writes its argument to the console and then moves to the next line.'Hello, World!'is a string literal that contains the message we want to print.
To compile this code, you would need a Pascal compiler such as FPC (Free Pascal Compiler) or Delphi. The command to compile this program using FPC might look like this:
fpc -o HelloWorld HelloWorld.pas
This will create an executable file called HelloWorld that you can run to see the output.
Note: This code is written in Modern Pascal syntax, which was introduced with Pascal 7.0 (FPC 2.0). The classic Pascal syntax would be slightly different, but this should work fine with most modern Pascal compilers.
