Solution

//dt = data table("FinalBiningTable"); // Uncomment for your table

dt = open**(** "$sample_data\Big Class.jmp" **)**;

column_list = dt << **Get Column Names(**string**)**;

if **(**!contains**(**Column_list, "N(P, F)"**)**,

dt << **New Column(** "N(P, F)",numeric, ordinal, << **Set Each Value(0))**;

**)**;
