2.7.2 Block Comments

Entire blocks of code can be commented by enclosing the code between matching ‘#{’ and ‘#}’ or ‘%{’ and ‘%}’ markers. For example,

function quick_countdown
  # Count down for main rocket engines
  disp (3);
 #{
  disp (2);
  disp (1);
 #}
  disp ("Blast Off!");  # Rocket leaves pad
endfunction

will produce a very quick countdown from '3' to "Blast Off" as the lines "disp (2);" and "disp (1);" won’t be executed.

The block comment markers must appear alone as the only characters on a line (excepting whitespace) in order to be parsed correctly.
