I'm new to SPSS and I have some "under the hood" work to do with principal
component analysis.  Can anyone provide me with the SPSS syntax for reading
the active dataset to a matrix, and then writing the resulting matrix to the
another data set.

Read active data set.
(I'll do some matrix computations I know how to do)
Write resulting matrix to a new data set.

Thanks, Matt
