Subject: [ruby-talk:12229] random chars

Hello everybody, I think/hope I have some simple questions.

I've writte a little program that makes a copy of itself but
makes some mistakes. But I have one problem:

I'd like to delete one character of the variable string, but
delete! would delete this character in the whole string an
not only at one position. Does anyone how it works. The shorter
the expression the better.

Thanks for your help, Urban

  string = lines[changeline]
  changechar = Kernel.rand(string.length-1)
  chars = Kernel.rand(127).chr
  2.upto(Kernel.rand(5)) do
    chars = chars + Kernel.rand(127).chr
  end
  string[changechar] = chars
  lines[changeline] = string
end
lines.each {|item| put.puts(item)}
