HI everybody, I try to run this progam with SAS University: proc print data=peuplier; format clone varfmt.; title 'Impression du fichier peuplier'; run; proc glm data=peuplier; class clone; model diametre=clone; run; and this error message appear: Invalid characters were present in the data. When i try proc mixed instead of proc glm, it's working.... Someone could know why? My classmate is able to run the same program with proc glm, but not me..... thanks.
