Thank you very much for your answer and sorry for mine being late. Well it's a bit strange. I replaced the strange character by run; If the path is the path to the SAS code file, there is no error but I have an empty array with around 1800 columns/variables and no row. Now if I replace the path by the path to adult.dat that I saved as a link as you showed me, I have this error : ERROR: Physical file does not exist, /pbr/biconfig/940/Lev1/SASApp/D:\Divers\Dossiers et Thèmes\Maths Informatique\Informatique\IA\IA_projet\MyOwnModels\LogisticRegression\adult.dat. NOTE: The SAS System stopped processing this step because of errors. WARNING: The data set WORK.ADULT may be incomplete. When this step was stopped there were 0 observations and 1238 variables. WARNING: Data set WORK.ADULT was not replaced because cette étape a été interrompue. In the path, I tried both upper case ADULT.DAT and lowercase adult.dat (my file is saved in lower case) and none of these is working. I thought it might be the withespace in the file path causing the problem, but when I use it with the sas Code file name instead of adult.dat there is no such error so I'm really lost. I joined the printing of the physical location of my file and of the errors. Thanks again, Geoffrey.
