How in Pascal to create an array of the length that the user entered?

Question

Pascal

In general, what I need in Python looks like this:

n = int(input("Введите число: "))
a = [i for i in range(n)]

How to do this in Pascal? On the Internet, I was advised to simply declare the array in this way: But something tells me that this is a bad form.
Var a: array[1..999999] of integer;

Answer 1

Use dynamic array

var
  a: array of integer;
 
begin
  setlength(a, 10);
 end;
