When I first read the question, I wasn't sure what the problem was.  But then, I've not yet had the pleasure of taking GENLINMIXED out for a test drive.  A quick glance at the FM (i.e., the "fine manual", as in RTFM) suggests that rather than using the "BY factor WITH covariate" method, GENLINMIXED uses the variable levels to distinguish between factors (nominal & ordinal) and covariates (scale).  Perhaps someone who has used GENLINMIXED can confirm.

HTH.
