I have the following code with an if-then-else statement.  Both the If and the Else are running.  The value of &nrows being input to this dataset = 1 which meets the IF condition.  I know the Else is running because after the code executes "cancel" = the value from the Else do statement.     data _NULL_;      if 0 then set specs_step2 nobs=n;           if &nrows > 0 then do;                %put NOTE: Program terminated because there are missing IRNs in the data.;                %put See the Results or Output window for the cases where these are needed.;                %put Putstate3 = There are &nrows.
