https://communities.sas.com/t5/Statistical-Procedures/Proc-Reg/m-p/23918#M821 There is no class statement in proc reg, so how should I use the discrete predicted variable in proc reg ? <BR /> <BR /> Or in that situation I need to use proc GLM. <BR /> <BR /> Or it doesnt matter as regression dont have any assumption with predcitors ?

Reg will not 'lump' them together for the inclusion or exclusion in the various stepwise models; if you want to do that, you will need to manually implement the steps in GLM.
