Dear listers:
I sent this subject yesterday(or the day before yesterday), and got the
reply from Mr. Nick.
I do appreciate your assistence on this subject.
And I did try to use Auto dataset and see whether for a 2XC(C>2) table, I
can obtain Fischer exact p-value or not.
And It does work.

However, the "auto" dataset is small, the observation is approximately only
70. Hence, STATA takes few seconds to calculate the Fischer Exact p-value
for this 2X5 table(foreign vs rep78).
My problem is that my dataset is not so big(the number of observations for
comparison is approximately 2000). This moring, I use -tabulate- to obtain
the Fischer exact p-value. However, up to now, I still can not get the
results.
(This means that for a computer with 312M memory, STATA needs at least 10
hours for calculating Fischer Exact p-value.)
I am just wondering whether there is any lister having this kind of
situation before or not, and how did you solve this situation?

Up to the moment I send this email, I still can not get the result yet.
Thank you very much for any of you who can respond this email. Thanks again.

JT
