PROC MIXED: Output data tables header Col1, Col2, ...... NO variable names displayed

[PatrickYang]

We are trying to follow the SAS PROC MIXED paper: http://www2.sas.com/proceedings/sugi29/198-29.pdf

We are attempting to reproduce Tables 3 and 4 on Page 6.

However, we could not get the tables to display actual variable names (U1, W1, U2, W2,...,). Instead, it is Col1, Col2, Col3,... that are displayed.

Did we do anything wrong??????
