A quick possible fix:I find using the options button in the repeated measures window and putting the factor of interest in the display means for window, then clicking on compare main effects allows you to choose various adjustments for multiple tests. This will handle a constant covariate (varying across subjects which I would assume age usually is).

For a varying covariate (ie one that varies with the level of the repeated measure) one would need syntax unless you are lucky enough to have the version 6.0 dialogue box.
