Dear SASKiwi: Thanks a lot for your exhaustive search and info. I saw the link. There is a Proc in SAS/OR but nothing related to the functionality of SAS/Genetics.

By the way, the first ERROR I describe in my post, is something related to my system configuration or I may have another problem. Again, thank you for your help and info. All the best, Carlos
