Charles,

My reading of the manual suggests that you may
be attempting to work with the wrong output file
or at least  not the easiest to process.

The OUT=  file has original variables and the
Canonical Variable Scores as Can1 Can2 ... up to NCAN variables.
These are centered with mean zero & pooled within variance = 1
These could be input to FACTOR as variables and rotated any which way.

The OUTSTAT= file is really a heterogenous collection of  structures
To get at a particular structure you need to
select based on _TYPE_ & _NAME_

I expect that a correlation matrix  produced  from
the NCAN vars in the OUT file would  be the same as
the rows of the OUTSTAT file selected where _TYPE_='PCORR'
