Ruby global variables are not accessible via hosting API.
ScriptRuntime.Globals refers to global constants (constants defined on Object).
ScriptEngine ruby = IronRuby.Ruby.CreateEngine();
ruby.Runtime.Globals.SetVariable("Bar", 2);
ScritpScope scope = ruby.CreateScope();
scope.SetVariable("frm", 123);
ruby.ExecuteFile("test.rb", file);
where test.rb is
p frm, defined?(frm), p Bar
prints
123
Nil
2
frm is looked up via method_missing on the main object.

2nd question why global variable does not work?
Form frm = new Form();
ScriptEngine ruby =
IronRuby.Ruby.GetEngine(IronRuby.Ruby.CreateRuntime());
ruby.Runtime.Globals.SetVariable("frm", frm); ScriptScope scriptscope =
ruby.Runtime.CreateScope(); ScriptSource script =
this.scriptengine.CreateScriptSourceFromFile("test.rb");
scriptscope.SetVariable("frm",frm);
ruby.Execute(script.GetCode(),scriptscope);
-----------------------------------------------
test.rb
defined? $frm
---------but it is nil....
defied? frm
it is ok...
