Test for Trend when Frequencies already known

Is there a way to calculate the p-values from Cochran-Armitage Trend Test when I am only given frequencies like so:

data have;
 input dose $ response $ count;
 cards;
 10ug  yes 3
 20ug  yes 1
 30ug  yes 1
 Plac  yes 2
 10ug  no  1
 20ug  no  3
 30ug  no  4
 Plac  no  1
;
run;

Or do I need the combinations repeating for

proc freq data = have;
 tables dose*response / trend;
run;

You can use the WEIGHT statement

proc freq data = have;

weight count;
tables dose*response / trend;
run;
