&amp;lt;P&amp;gt;Model 204 uses instructions which are not supported on the IBM System/360 (or equivalent) and requires the System/370 instruction set. Since Model 204 cannot proceed further, it will terminate with a return code of 4 in the initialization step. &amp;lt;/P&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;&amp;lt;b&amp;gt;System manager response:&amp;lt;/b&amp;gt; You cannot upgrade to a Model 204 release past Release 7.1 because of this restriction. [[Contacting Rocket Software Technical Support|Contact Technical Support]] for assistance. &amp;lt;/p&amp;gt;&lt;br /&gt;
