Can I use proc glm or linear regression comparison between to groups?

Typically this would only be done via PROC GLM and not REG. That is, if I understand the problem properly, where "to [sic] groups" indicates a classification variable is used as the independent (or predictor, or X) variable, such as groups like "male" and "female".

If your comparison between two groups involves a single variable, use proc glm. Regression is for looking at the relationship between different variables.

Examples:

Comparing the weights of men and women : proc glm

Looking at the relationship between weight and height : regression (proc reg)

In SAS, there are also many other procedures for addressing both these tasks.

Thanks.
