for example. you created a macro called "time" and stored it at library "perm"

libname perm 'd:\peter.hu';

OPTIONS MSTORED SASMSTORE=perm;

%macro
   time/store source;

    %put now is %sysfunc(time(),time11.2).;

%mend time;

when you want to invoke time macro, just type as following:

libname perm 'd:\peter.hu';
OPTIONS MSTORED SASMSTORE=perm;
%time
