Right now i am using the following code which is inside a macro which runs for multiple datasets.

data _DSN2; if 0 then set _DSN1 nobs=nobs; if nobs=0 then do; call symput("nobs", "0"); &psid="&sub"; visn="NO DATA "; output; end; run;

The above helps me display "NO DATA" in my output report because i know that the data which has no observations has a variable called "visn".

When i run this on another study where another data say, DEATH has no observations, in the report "visn" doesnt exist. Variables like dthdt,dtdiscon,dthrsn..are there.

So when i run the above code my report just has blank values under these variables. I want to put "NO DATA" under first variable DTHDT. so the program should create a macro variable which stores the first variable name in the datasets. I can then just say &var="No DATA"

I hope iam clear.
