In the following code, the variable SAP has four categories. My question
is: is it necessary to create dummy variables for such a variable in Proc
Mixed? Thanks in advance for your help.

 proc mixed data = a1bir_mix noclprint covtest noitprint;
  class sub sap;
  model weight = sap loneprop lt9_tot tdvce_10 avh_1000
