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 to be parsed correctly.
