deleting a row

[wajmsu]

Hi,

Below is a table with matched dataset (cases and controls). Out of the five cases, first four cases have a duplicate case with missing values for all variables. How can I delete these row?

Thanks

run;

Hi PGStat,

I understand the code will keep thosr rows which do not have missing values. In that scenario, my all cases have first column with missing value. I am afraid it will delete that caso also and this way my all cases would be lost. Please guide me.

Thanks

if cmiss(ControlId,id,age,edu,race,parity,wt,ht,opwo,fev)= 10  then delete;

Hi Ksharp,

Please confirm 10 represents the number of variables in the parentheses.

thanks

Yes. Confirm. I thought you know function CMISS() , didn't you ?
