Execute different events. The TRIGGER statement executes another event. For example, the start section of DOC triggers the start section of MYTEST and OTHEREVENT. MYTEST has a start section, so output is generated. OTHEREVENT is stateless (no start or finish sections), but output is generated.

         put 'finish of doc' nl;
         trigger mytest start;
         trigger otherevent;
         trigger mytest finish;
