You never assign $mode. What is it supposed to be for? You also never use the 2nd argument to read_cal

Your test for /^\s*$/ is redundant, because you've already removed all whitespace, and you test for an empty line.

I think your main problem is that you should have a next after the recursive call, or put the rest of the stuff in an else. You don't want to read a file and parse the line, do you?
