title: How do I define AMPL like sets and parameters in Julia+JuMP?
body: <p>I need to define some constant parameter in Julia+JuMP, similarly to what you do in AMPL when you define</p>
  
  <pre><code>set A := a0 a1 a2;
  
  param p :=
  a0 1
  a1 5
  a2 10 ;
  </code></pre>
  
  <p>How do I define something like <code>A</code> and <code>p</code> in Julia?</p>
