Hi, I 'm running SAS Studio https://odamid.oda.sas.com   There are 12 variables in my data set from aa to ll The code contents many PROCs which work well except GLM and ANVOVA . What can it be ?   I use dot as decimal separator , perhaps I should use coma ?   If the data work with a PROC MEANS it should work with a proc GLM, right ?   50 0 1 1 160.1390174 112.8613466 132 70.666 0.824283814 0.626131108 522.666 273.000364 50 0 1 2 50.94657769 63.80558666 34.667 12 0.680457875 0.188071306 245.334 114.752164 50 0 1 3 139.4144644 136.0067384 77.333 108 0.554698541 0.794078303 360 275.421203 50 0 1 4 165.7679449 94.30003653 74.666 78.667 0.45042484 0.83422025 338.666 260.067981 50 0 1 5 99.56423276 88.25156971 93.334 40 0.937424991 0.453249728 425.334 187.815803 50 0 1 6 101.4125085 139.7460904 64 17.333 0.631085858 0.124032092 362.666 241.158599         thanks   142 proc glm data=fente4; 143 class cc; 144 model ll2=cc; 145 means cc / duncan; 146 run;   ERROR: Invalid characters were present in the data.
