I am using the pickaxe example to help learn how it is writen.
Thank you once again.
Becker

my run program
[code]
require "C:\\ruby\\Test"
t =3D Test.new()
t.add("Bill Chase")
[code]

my code example from pickaxe  saved as a .rb
[code]
#include "ruby.h"
static VALUE t_init(VALUE self)
{
  VALUE arr;
  arr =3D rb_ary_new();
  rb_iv_set(self, "@arr", arr);
  return self;
}

static VALUE t_add(VALUE self, VALUE anObject)
{
  VALUE arr;
  arr =3D rb_iv_get(self, "@arr");
  rb_ary_push(arr, anObject);
  return arr;
}

VALUE cTest;

void Init_Test() {
  cTest =3D rb_define_class("Test", rb_cObject);
  rb_define_method(cTest, "initialize", t_init, 0);
  rb_define_method(cTest, "add", t_add, 1);
}

[code]
