Trying to find out any difference exist among the groups?
Mean difference? Variability difference? Distribution difference? Other?

You also could do PROC GLM for ANOVA, it is robust for non-normal data. Or you could try Non-parameter method SAVAGE test,check the last example in PROC NPAR1WAY documentation.
