ARRAY is giving me character conversion log message

I am receiving a log message "Character values have been converted to numeric values at the places given by" in my " do over _value; " statement. This caused bc the dataset is empty.  How do I fix this log message? thanks
 

data pfinal1;
	merge  tmerge_xl  tmerge_xl3 ; 
  	by ord1 aebodsys  ;

	 if ord1 in (1 2) then do;
	     array _value  ctrtg1 ctrtg2 ctrtg3 ctrtg4 call ; 
		 	 do over _value;
		     	         if _value = "" then _value="0 (0.0%)";
		 	 end; 	 
	  end;
run;

So those variables don't exist in this case? Have you tried explicitly listing the types on the array statement and see what happens?

array _value (*) $20. ctrtg1-ctrtg4 call;

Set the variable LENGTH (and type) in the ARRAY statement.

array _value $20 ctrtg1-ctrtg4 call ;
