We have a much better method already implemented called labeled loops. It was
discussed here quite a bit. General:

for a = 1 to length(lines) label "line_it" do
    line = lines[a]
    if match("/*", line) then
        while 1 do  --- we are going to eat all comment lines.
            -- read line
            -- test end of comment?
            if end_of_file then
                 exit "line_it"
            end if
        end while
    end if
end for
