I am doing my undergraduate interdisciplinary project individually. I thought, i need to work with sas software, because it will be my advantage in the future. basically, this is for my project.

Does your PermNo variable actually contain text "(none)" or is it a SAS MISSING value? If the later

 

Proc freq data = have;

   where not missing(permno);

   tables secid;

run;

will give the count of each secid and the cumulative at the end of the table the overal count.

 

If the value of PermNo actually contains text of (none)

then

Proc freq data = have;

   where permno ne '(none)';

   tables secid;

run;

will do the same thing.

sorry for inconvenience. I wrote down "none" in some case, there is just "."(dot).

I do not mean about frequency, i mean, counting total number of secid per year that has permno.
