The following step restores all the default macros and macro variables and deletes the modified templates:

%ProvideSurvivalMacros

proc template;
   delete Stat.Lifetest.Graphics.ProductLimitSurvival  /
          store=sasuser.templat;
   delete Stat.Lifetest.Graphics.ProductLimitSurvival2 /
          store=sasuser.templat;
run;
