Define a new tagset. The DEFINE TAGSET statement creates a new tagset called tagsets.mytags. The PARENT= attribute is used so that the new tagset tagsets.mytags inherits events from TAGSETS.CHTML. Note that the ODS PATH statement is specified at the beginning to establish the search path.

ods path sasuser.templat (update)
   sashelp.tmplmst (read);

proc template;
   define tagset tagsets.mytags /store=sasuser.templat;
      parent=tagsets.chtml;
