A common method for defining librefs through code is to %include a file
in the server's OPTIONS property.

As a workaround, use the following code in the %included file to define
the librefs.  It will check for the existence of the library before
assigning the libref:

   /* This macro assigns a library and detects whether it exists */
   %macro eglibassign(libtoassign, libpath, libeng, libopt);
   %local success;
    %if "&libopt" ne "" %then
     %let success = %sysfunc(libname(&libtoassign, &libpath, &libeng,
   &libopt));
    %else %if "&libeng" ne "" %then
     %let success = %sysfunc(libname(&libtoassign, &libpath, &libeng));
    %else
     %let success = %sysfunc(libname(&libtoassign, &libpath));

   /* if the library does not exist, CLEAR it */
   %if (%sysfunc(libref(&libtoassign)) ne 0) %then
    %do;
       libname &libtoassign clear;
       %put WARNING: Libref &libtoassign could not be assigned;
    %end;

   %else
       %put NOTE: Libref &libtoassign was successfully assigned;
   %mend;

   /* Example usage */
   /* assign desired libraries using this macro */
   %eglibassign(test, c:\DoesNotExist);
   %eglibassign(test2, u:\VoterData);
