Quick Start

Write a file, run it. That is the whole page.

If you are new to programming, prefer Lesson 1 — Your first program after Install or the Playground.

Hello

Create hello.echo:

say("Hello, Echo!");

elang hello.echo

Or open a desktop editor (IDLE-style) and click Run:

elang ide hello.echo
# or empty buffer: elang ide

Output:

Hello, Echo!

Rules you hit immediately

• Instructions end with ;.
• Groups of instructions use { }. New lines alone do not end an instruction.
• Spaces at the start of a line are for reading. They are not how Echo groups code (unlike Python).

Wrong (missing ;):

say("Hello, Echo!")

Right:

say("Hello, Echo!");
