Is there a way to get a 'Power' column in Proc GLM?

MI was looking up information on another topic when I came across some ANOVA output from SPSS:

Source SS df MS F p eta2 Power

X1 0.08 1 0.08 0.02 0.90 0.0012 0.05

X2 etc

The interpretation of the output was, "X1 was not signficant (p=0.90), but the study lacked sufficient power in that test (0.05)."

I thought that would be very important information to have and would like to see it in my SAS output. I did some searching and found Proc GLMPOWER, but I don't think it is applicable.

Is there some other way to get the power associated with each variable in the ANOVA output?

(I'm using SAS 9.3)

SAS has a proc power but is really intended for use in study planning. Look to see if you have the SAS Power and Sample Size Analysis installed.

Also I am somewhat leery about assumptions that may be going into the ANOVA regarding the actual sample design to get the reported power.
