st: Beta distribution

Hi Listers,
Is it possible to generate a random beta variable with
-a fixed/predetermined range of possible values, as well as
-a fixed mean, but still have
-the ability to vary the shape parameters meaningfully?
This is more a distributions question in general than a stata question in particular, but I would want to implement using stata.
I want to test the power of a mean comparison test (with means/mean difference specified a priori) for variables with fixed range of values (0 to 2 in this case) but where the underlying distributions are anyone's guess. That is, I want to be able to experiment w/ different distributional properties while maintaining the mean and range.
Would appreciate any guidance, including alternative approaches.
Thanks,
Rob
