And to expand on that.
Correcting your code becomes:
if compare( '<', line[i]) = 0 and
     compare(line[i+1], 't') = 0 and
        compare(line[i+2], 'd') = 0
      then
     puts(1, line)   -- output is:  ABC

and is the same as:

if compare(">td", line[i..i+2]) = 0 then
  puts(1, line) -- output is: ABC
end if

You can also use: equal(">td", line[i..i+2])
