Error illegal use of array

[rylife]

My code is returning an error an am not sure why

Original code

DATA scoredata1;
set scoredata0;

Array sc(3) score1 score2 score3;
Array new (3) ns1 ns2 ns3;
DO i=1 TO 3;
IF sc(i)=777 then new(i)= .;
else if sc NE 777 then new(i) = sc(i) ;   
end;
run;

else  new(i) = sc(i) ; 

is all you need i think 

The error is you are mising the array index while referencing in your

else if sc NE 777 then new(i) = sc(i) ; 

which should have been

else if sc(i) NE 777 then new(i) = sc(i) ;

Thanks!

Or even terse would be just one statement and that is

if sc(i) NE 777 then new(i) = sc(i) ; 

Coz new(i) is anyway initialised with .
