Hello World

This is the source of the traditional first program:

'' This is a comment. The compiler ignores everything after ''.

'' print writes a line of text to standard output.
print "Hello, world!"

Output

Hello, world!

A tiko program needs no main procedure and no boilerplate around it. The statements at the top level of the file are the program, and they run from top to bottom. print writes its arguments to standard output and ends the line.

Compile it with the tiko command and run the result:

tiko hello.tiko
./hello

The program takes the source file's name, so on Windows it is hello.exe. -o names the output yourself, exactly as written: -o greet writes a file called greet, so on Windows give it the extension, -o greet.exe. tiko produces one self-contained executable: there is no runtime to install beside it.

Activities

1. Change the text and print a second line under the first.
2. Compile with -v added to the command line and read the steps tiko takes to turn the source into a program.
