How do I create a text box to display scrollable text I send it via script?

Question

I'm currently making a game where I want to display text to describe what's happening. How can I send text to a text box without erasing the previous text, making it scroll up? Something like an in-game console where I could just print text on specific actions. Also, how could I erase "old" text (text that has been "scrolled up" x times)? Here's what I'm doing (I'm still learning how to code), and I realized I'm starting to run out of space :p

 function OnGui () {
 
 if (money < 15)    
 {
 GUI.Label (Rect(10,260,200,200), "You have no money to buy food");
 }
 
 if (actionsPerDay == 0)
 {
 GUI.Label (Rect(10,280,400,200), "You're tired and need to go to sleep");
 }
 
 if (hunger == 0)
 {
 GUI.Label (Rect(10,300,400,200), "You're starving! You need to eat urgently!");
 }
 
 }

An example in C# which uses a Queue instead of List:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
  
  
 public class playerLog : MonoBehaviour {
  
 public int maxLines = 8;
 private Queue<string> queue = new Queue<string>();
 private string Mytext = "";
  
 public void NewMessage(string message) {
 if (queue.Count >= maxLines)
 queue.Dequeue();
  
 queue.Enqueue(message);
  
 Mytext = "";
 foreach (string st in queue)
 Mytext = Mytext + st + "\n";
 }
  
  
 void OnGUI() {
  
 GUI.Label(new Rect(5, // x, left offset
 (Screen.height - 150), // y, bottom offset
 300f, // width
 150f), Mytext,GUI.skin.textArea); // height, text, Skin features}
 }

You could then use a GetComponent and pass messages to playerLog.NewMessage(newMessage), or declare that bit static so all classes can pass things to it w/o GetComponent references, etc.
