Illegal reference to an array

393310 — Fri, 22 Oct 2021 21:34:31 GMT

Hi all, I am struggling with my do loop. I continue to get "illegal reference to an array for the "categorical and npredictors" array, but it works just fine for my first array "var_list." Is there something that I am missing? I am using SAS 9.4. I also tried to run the arrays in separate data steps and it gave me the same error.

You need the (index-variable) on the LHS of the = as you have on the right.

 categorical[j]=vvalue(categorical[j]);

You cannot have a non-array variable with the same name as the array.

Variables can't have the same name as arrays.

I usually use _ in front of my arrays, as a coding standard it helps for sure.

array _categorical(*) ... ;
do .... ;
categorical = _categorical(i);
....
