The new version of ASREML gives some additional information in the .asr file. Beside each Compnt/Stderr value there is a letter.  It seems that uses P for components estimated using !GP, U for !GU and S for ?

I got the S when estimating the covariance matrix for a polynomial regression. Even when the program converged, I'm very suspicious about the estimates: the value of Compnt/Stderr was the same for all elements of the matrix. Does anyone have an idea what the S mean?
