in reply to Crossword helper

When I run it, I get the following error:

exists operator argument is not a HASH element at ./crossword.pl line 61.

Any idea why?

From perl -v:

exists on arrays (Re: Crossword helper)

    (From memory) Perl 5.6 extended the exists function to work on array elements and functions. Replace it with defined to get nearly the same meaning, close enough to the same to work for this script.
