PROC ds2 output variable not creaed in the dataset

[jins]

If i use this code to create a data set, the day_tran variable is not created.

But if comment out declaration, then the variable is created but with a log message "WARNING: Line 570: No DECLARE for assigned-to variable day_tran; assuming type double."

Is that normal or is there way to counter this message?

method run();

declare double day_tran;

set dsets.ersplita;

day_tran=date2days(to_double(startdt),to_double(startdt));

end;

If you want it output to the dataset, you have to declare it outside of a method.  For example:

data class;
  set sashelp.class;
run;
proc ds2;
data wantds2;
dcl double day_tran;
method run();

set class;
day_tran=intnx('year',0, age);
end;
run;
quit;
