The value returned as the second value of Get_Line is called Last, and
refers to the last index in that contains a valid value read in.  It is
prefered that you name that object last, as in

declare
   Name : String (1 .. 50);
   Last : Natural;
begin
   Get_Line (Name, Last);
...
end;

But when if I invert them, GNAT is not happy and it doesn't work:

...
begin
        get(number);
        ...
        get_line(name, number2);
... 

What am I missing?

What do you mean by "GNAT is not happy." Do you mean that the program
wouldn't compile, or that it does compile, but runs with an exception, or
runs but delivers incorrect results?

It is difficult to provide help when you use non-technical descriptions as
"not happy."

And what is Get?  Is it from Ada.Integer_Text_IO?  Or some instantiation of
Ada.Text_IO.Integer_IO?  Or something else?

If you're getting an exception during Get, it may mean that you're trying
to enter a number that doesn't have the format required for an integer
literal.
