Phil,
Yes, you have a multivariate repeated measures, just as you thought. Look at
the documetation for GLM Repeated Measures in the syntax references and, in
particular, for the measured command where the example gives the setup for
just such as model.

>>In a case where a mixed between-within ANOVA seems like the right
statistical tool, does anyone know if its possible to use this tool with
several "within" variables in the same model?
For example, suppose i have measures for 10 different continuous variables
at time 1, 2 and 3. These variables represent my "within-subjects"
variables and time represents my "within-subjects factor." Next, I have a
categorical grouping variable representing the "between subjects" variable.
Am i confined to testing one continuous variable (with 3 measurements) at a
time or is there some way to assess the three measurement points among all
10 variables at once?
I guess i am looking for the "within-between" equivalent of a multivariate
anova that allows assessing the significance of several dependent variables
at once; only in this case, i have multiple time measurements for each
dependent variable. Otherwise, I am concerned that executing 10
within-between anovas dilutes my alpha value.
Any ideas or insight would be greatly appreciated!
