OK, got it. I modified my program and I get what I want now. Thanks 
much.

[root@hoho4 ocr]# cat test.rb
    constant = '31.12.2006'
puts "constant " + constant
    modify = '40.01'
puts "modify " + modify

   variable = constant.dup   <<<---- Added the .dup

puts "variable " + variable
puts "constant " + constant

   variable[0..1] = modify[0..1]

puts "variable " + variable
puts "constant " + constant

[root@hoho4 ocr]# ruby test.rb
constant 31.12.2006
modify 40.01
variable 31.12.2006
constant 31.12.2006
variable 40.12.2006
constant 31.12.2006  <<--- OK, it stays 'constant'
