Turbo Pascal. Reminds me of high school in the mid Eighties.

program HelloWorld;
begin
WriteLn('Hello World')
end.

Hello everyone,

Just an idea I thought might be interesting. How many different computer languages can we represent with just a simple "Hello World"...
Click to expand...
(my emphasis).

I submit this example as the simplest...

Since the Apple Basic interperter (on the Apple I and II) was always available for use, except when another program was in control (and of course, no lowercase was available). At the prompt simply type in:

PRINT HELLO WORLD
and
HELLO WORLD
appears on the screen.

No need to clear the screen or number the command(s).

(I may get into a semantics issue with this one).

Waiting for BBC Basic, 8086 asm, and Delphi.

I was thinking delphi should be much like Pascal. The first few examples I found were too complex. But I found this. As you can see it is the Pascal program with a few lines to setup the IO and such.

Belated thanks guys.
Like the last one. The Eric Isaacson A86 version.
I used to play with that.
Had an Acorn Electron that used BBC Basic. My first computer.
Played with Delphi ten years ago.
