SUPRtool question

I have something that is I2 in one dataset and J2 in another.
I am doing extractions...

        output from the first dataset
        output and append from the second

The problem is that the second part of this bombs because
the datatypes don t match.  (It tells me that the output size
is the problem, but all other fields are idential strings.)

Suggestions?

Thanks in advance!


p.s. Is there a SUPRtool newsgroup these postings belong in?
