HI All,
i was not comfortable not having any value after "NE", am i understanding it correctly as per my log message in Below program??
i read some documentation , https://v8doc.sas.com/sashtml/macro/z0543542.htm
and also referred Carpenters's Guide to Macro, Still not clear .
I am not clear what "NE" is comparing against!!
%macro jack(vals);
%if &vals. ne %then %do;
%put "Note:Has some values, therefore logical expression resolves to 1, which is True";
%end;
%else %do;
%put "Note:Does not have any value, therefore logical expression 0, which is false";
%end;
%mend;
%jack(nothing);
%jack();
So, is it going to be true anything except Missing values for &vals.!!
Thank You,
