What are some alternatives of Generics Collections TStack?

Question

I want to store some string data into a stack.

The Delphi Documentation for System.Generics.Collections.TStack is for Delphi XE4.

I read the answer of Mr. Heffernan in Missing units (IcePack, Generics.Collections)

What are some alternatives of stack aside from arrays?

Answer 1

Probably you are trying to use non-generic stack (that lives in System.Contnrs).
Here is full working example for generic TStack<>:

program ProjectC;
{$APPTYPE CONSOLE}
uses
  System.SysUtils,
  System.Generics.Collections;

var
  Stack: TStack<Integer>;

begin
  Stack := TStack<Integer>.Create;
  try
    Stack.Push(1);
    Stack.Push(2);
    while Stack.Count > 0 do
      Writeln(Stack.Pop);
  finally
    Stack.Free;
  end;
  Readln;
end.
