Re^2: How to clean an array of strings after a split

Thanks. I think I like this approach best because I don't need to concern myself with ensuring there are enough pipe symbols to suffice.

Actually, if you used kcott's suggestion here and `split` into a named array, e.g. `my @fields = map { ... } split ..., $str;` you wouldn't have to worry about how many pipes there are and 'uninitialized' variables: you get what you get, it's all defined, and it's easy to test how much you've gotten by taking the size of the array and to iterate over the array. Rather than writing `$var``n` you write `$fields[``n``]` instead, but 0-based. But I assume you have your reasons for preferring individual named variables...	[reply] [d/l] [select]
