Subject: Re: Need a range, but not getting it. . . .

Try...

files = [ARGV].to_s
files.gsub!(/\-/, "..")
puts files

However, I *think* that ARGV is already a string? so that to_s in the first line may be redundant.

Your problem was that, although gsub! (with the !) normally modifies the receiver, 'files' wasn't the receiver (to_s was), so you weren't actually changing 'files'.
