Thanks Austin,

For the table I showed, I get:

scalars:
                  r(N) =  861
                  r(r) =  2
                  r(c) =  2
            r(p_exact) =  4.79750510923e-07
           r(p1_exact) =  2.92991198169e-07

I'm interested in the two sided p so I did:

ret li p_exact

scalar r(p_exact)  =  4.79750510923e-07

Unfortunately what I'm actually doing is around 3500 tables and I'd really like to scan the output and see:

Fisher's exact =                 0.00000

so I can quickly pick out tables with p < .00001. I really do want to change the display format!
