We start with a simple Hello World example. It contains only a single non-empty cell. In this cell a print function is called using the markup <<@print>>. This function uses a single variable argument, also called print. This variable is assigned using the markup <<\$print="Hello World">>.

If Respix is executed, the print function replaces itself with the value of the variable print.
Variable markups are removed afterwards.
