Trailing Correlations

Helle there!!!

I wonder if anyone has any idea how I can automatate correlation creation for a 100 row set of data. I need SPSS to create correlation matrix for the 30 periods - starting with the 1 to 30 period, then 2 to 31 period then 3 to 32 period...up untill the 70 to 100 period. Do you think this can be scripted? Or do you know of any SPSS-devoted forum around?

Thanks a lot!!
