From SAS V6.08 through SAS V9.2, the SAS Macro Facility was erroneously evaluating expressions at macro compilation time which defined the default value of keyword parameters. This was a change from SAS V5.18. At macro compilation time, the SAS Macro Facility should have only been evaluating %STR and %NRSTR quoting functions used in the default value expressions of keyword parameters. The correct time for full resolution of default keyword parameter expressions is at macro execution time.

Sample code that incorrectly evaluates %SYSFUNC at compilation time:

   %macro A(B=A %sysfunc(putn(&xx,2.)));
     %let xxxx=%sysfunc(today()); 
     %put %unquote(&B.); 
   %mend A;
