MARK 3.1: dimension limits?

[cooch]

A colleague recently ran into a situation where she started receiving error message which looked suspiciously like 'exceed array dimensions' sorts of problems - lots of years of data, lots of parameters (>500), gigantic design matrices.

Are there any limits to the 'dimension space' for MARK, and she suspects?

Thanks (Gary)

If it helps, her machine has 1 GB of RAM, so that is unliekly to be the limit.
