Hey guys,
I'm trying to add a new value (variable value) to a list inside a function, each time the function has been called.
No matter what I tried, the list is not getting any value.
Any advice?
Adding the example of the code
I think it is better idea to return the new column and then add that outside of the function call
Names Default To Here(1);
dt = Open("\\VMSPFSFSLC001\F28_PLI\SQL\FE SQL\Data\Oxide .CSV");
op_list = List();
add_new_operation = Function({dt, col_name, op, PLmin, PLmax}, {Default Local},
new_col = dt << New Column(col_name,
Character,
"Nominal",
Formula(
If(/*some conditions for the value*/
)
)
);
return(new_col);
);
sticol = add_new_operation(dt, "STI", 201405, 80, 2000);
Insert Into(op_list, sticol);
Show(op_list);
// This should also work
// Insert into(op_list, add_new_operation(dt, "STI", 201405, 80, 2000));
Full example
Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
op_list = {};
add_new_operation = Function({dt, col_name}, {Default Local},
new_col = dt << New Column(col_name,
Character,
"Nominal",
Formula(
col_name
)
);
return(new_col);
);
Show(op_list); // op_list = {};
Insert into(op_list, add_new_operation(dt, "name"));
Insert into(op_list, add_new_operation(dt, "age"));
Show(op_list); // op_list = {Column("name 2"), Column("age 2")};
And if you really want to insert into the list created outside of the function, remove {Default Local} from your function (there are also other methods) but I wouldn't recommend this. One reason being that now you have to have op_list always created before the function is called.
Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
op_list = {};
add_new_operation = Function({dt, col_name},
new_col = dt << New Column(col_name,
Character,
"Nominal",
Formula(
col_name
)
);
Insert Into(op_list, new_col);
);
Show(op_list); // op_list = {};
add_new_operation(dt, "name");
add_new_operation(dt, "age");
Show(op_list); // op_list = {Column("name 2"), Column("age 2")};
