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;

74 set scoredata0;

76 Array sc(3) score1 score2 score3;

77 Array new(3) ns1 ns2 ns3;

78 DO i= 1 TO 3;

79 IF sc(i) = 777 then new(i)= .;

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

ERROR: Illegal reference to the array sc.

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) ;

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 .
