SELECT WHEN in DS2

Luhan — Thu, 21 May 2020 15:46:42 GMT

Hi,

when I use SELECT-WHEN in a PROC DS2 and list more than 1 value after a WHEN, SAS throws an error: "Parse encountered constant when expecting ')'.

Is this behavior (which differs from a DATA Step) intended?

Example: The following code works as long as no additional values are added after a WHEN as shown in the commented line (uncomment and the error will occur):

proc ds2;

data _null_;

    method init();
        dcl varchar(8) test;

        test = 'b';

        select( test );
            when( 'b' ) put 'Beginning';
            /*when( 'b', 'B' ) put 'Beginning';*/
            when( 'm' ) put 'Middle';
            when( 'e' ) put 'End';
        end;
    end;
enddata;
run;
quit;

Try this:

select( test );
  when( 'b' )
  when( 'B' ) put 'Beginning';
  when( 'm' ) put 'Middle';
  when( 'e' ) put 'End';
end;
