I don't think that you can.<BR /> <BR /> You can do post-hoc tests in GLM with the TEST statement. I find it a bit more flexible than using the ANOVA procedure.<BR /> <BR /> You may also want to repost this question on the SAS Statistical Procedures forum for a broader viewing. Please include some code samples and more specificity in your question.
