Jako (programming language)

The Jako programming language for the Parrot virtual machine was initially created by Gregor N. Purdy as a "user-friendly mini-language,"^[1] and became the first Parrot-targeted language implementation to have subroutines.^[2] It is similar to Java or C++, but makes several large deviations, in some ways making it closer to Perl. Jako can be compiled into Parrot's assembly language, PASM, and then run on the Parrot virtual machine.

Hello world in Jako is:

use sys;
sys::print("Hello, world!\n");
