Using regex special characters from a string

Hi all, I have a script which takes a string of alphabetic characters as an argument, generates all combinations of the characters and all permutations of the combinations, then looks up each result in a list of valid words, if the result is a valid word it gets stored in an array. I would

Re: Using regex special characters from a string

Hi Jim, thanks for replying :) $word_list{$_} = 0; If you assign 1 to the hash value, you can dispense with the 'exists' in your test, below. #Here, using a hash looks much cleaner than iterating through an array push(@all_combinations, $temp_word) if (exists $word_list{$temp_word});
