ROC curves : cut-off estimation

Hi,

I needed to create a Roc Curve for my study. I used the Proc Logistic :

Proc Logistic data=table_donnees;
model spa=A_oed_D / outroc=roc1 roceps=0;
output out=outp1 p=phat;
run;

symbol1 i=join v=none c=blue;
proc gplot data=roc1;
title 'courbe roc';
plot _sensit_*_1mspec_ / vaxis=0 to 1 by 0.1 cframe=ligr;
run;

But now i need to estimate the cut-off for each point of my roc curve and i don't know how to do that with sas...
If somebody coud help me i will apriciate!!
