Using a permanent data set
If in a previous job you had stored the permanent data set SURVEY1 in the class sub-directory, then the following code

LIBNAME Library '/bios524/classlib';
PROC PRINT DATA=Library.SURVEY1;
  TITLE "Using a permanent data set";
  ID SUBJ;
  RUN;

produces identical results:
