Hi, I posted my simple module and test file at http://www.pastie.org/2025300. When I run my test under SciTE 1.74 with WinXP-Pro/SP3, I get the results shown below. In short, I fail trying to include the module using the name of the module or the name of the file hosting the module. Any correction to my misunderstanding would be most appreciated. Thanks in Advance, Richard >ruby TestMyMod.rb RUBY_VERSION = 1.9.2 RUBYLIB = K:\_Projects\Ruby\_Ruby__KeyModules Attempt to load MyMod ========== uninitialized constant Object::MyMod ========== Attempt to load SimpleMod ========== uninitialized constant Object::SimpleMod ========== List MyMod container, SimpleMod.rb Path = K:\_Projects\Ruby\_Ruby__KeyModules\SimpleMod.rb # SimpleMod.rb # K:\_Projects\Ruby\_Ruby__KeyModules module MyMod def say_hello puts "Hello from say_hello in MyMod" end end >Exit code: 0
