3. Membuat program Hello world

Buat hello.erl berkas

vim hello.erl

Tambahkan ini ke file

% This is a test Hello World Erlang Code
-module(hello).
-import(io,[fwrite/1]).
-export([helloworld/0]).

helloworld() ->
   fwrite("Hello from Citizix, Erlang World!\n").

Kompilasi dari shell Erlang. Jangan lupa tanda titik (“titik”) di akhir setiap perintah:

~> erl
Erlang/OTP 22 [erts-10.7] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [hipe]

Eshell V10.7  (abort with ^G)
1> c(hello).
{ok,hello}
2> hello:helloworld().
Hello from Citizix, Erlang World!
ok
3>

Anda telah berhasil menginstal Erlang di sistem Anda.
