polychoric seems to use version 8 and latter.

Hi all:

I'm trying use polychoric command to get correlation between categorical
variables. There are about 2000 observations.
Gender: male=1 female=2   and stress: yes=1 and no=0

I'm getting this "conformability error".

polychoric  gender Stress
conformability error
r(503);

Why am I getting this error?  I'm using STATA 7.
Please advise me. Thanks
Vinod
