Subject:      reading in a correlation matrix

Hi,
 
I'm trying to read in a correlation matrix I have and create a SAS data
set from it to then run a principal components analysis.  I thought proc
iml would be a good way to start, but when the 'create' statement runs, I
get a message stating there are no observations in the dataset.
 
I've included a log showing my attempts.  Any suggestions for running this
program more effectively, or more generally, how to read in a correlation
matrix into a sas dataset would be appreciated.
 
Thanks
 
Scot
