Hello to whomever can help

   value safdesc 0='Average or Above'
                 1='Below Average';
   value sizename 1='Small'
                  2='Medium'
                  3='Large';
   value vstfmt 0='staff only'
                1='physician';
   value spcfmt 1='oncologist'
                2='internal med'
                3='family prac'
                4='pulmonolgist'
                5='other special';
run;

data hosp;
  set sasuser.b_hosp;
  format date mmddyy8.;
  format visit vstfmt.;
  format code specfmt.;

The SASUSER library is read only in SAS University Edition, and you cannot save content to this library.

Delete the statment "lib=SASUSER;" or change it to another writable library.
