title: Does the whole linkage section return?
body: <p>In program a</p>
  
  <pre><code>EXEC CICS LINK
     PROGRAM(PGMB)
     COMMAREA(COMMA)
     LENGTH(LENGTH OF COMMA)
     RESP(CICS-RESP)
  END-EXEC
  </code></pre>
  
  <p>In program b</p>
  
  <pre><code>EXEC CICS RETURN
  END-EXEC
  </code></pre>
  
  <p>Does program b only return the commarea that program a passed? Or does it return the whole LINKAGE SECTION?</p>
