title: JCL SYNCSORT: OMIT and INCLUDE are not interchangeable?
body: <p>I'm getting different output for these two sort cards, can someone tell me why?</p>
  
  <p>1.</p>
  
  <pre><code>INCLUDE COND=((1,3,CH,NE,C'ABC',AND,5,3,CH,NE,C'PQR'),OR,
                (1,3,CH,NE,C'CAB'),OR,
                (1,3,CH,NE,C'CBA'),OR,
                (1,3,CH,NE,C'ABC',AND,5,3,CH,NE,C'PQR'))
  SORT FIELDS=COPY
  </code></pre>
  
  <p>2.</p>
  
  <pre><code>   OMIT COND=((1,3,CH,EQ,C'ABC',AND,5,3,CH,EQ,C'PQR'),OR,
                (1,3,CH,EQ,C'CAB'),OR,
                (1,3,CH,EQ,C'CBA'),OR,
                (1,3,CH,EQ,C'ABC',AND,5,3,CH,EQ,C'PQR'))
  SORT FIELDS=COPY
  </code></pre>
  
  <p>This is basically, INCLUDE when NOT-EQUAL and OMIT when EQUAL. </p>
