Not how I understood his simulation--looks to me like he's using each
column as the results of an iteration and just wants to save the last
100 iterations as the columns of an array.

If so, there's no reason not to do as the sample I posted earlier that
doesn't move any data unless wants to save those results in
chronological order--then he can reorder at the end before the saving
operation once instead of every iteration.

If that's what he's got to do but not how I read his posting.
