As you can see you don't lose the first 2, After that you want 4
elements on the same variable:
SetLength(Vetor, 4)
If you print the variable, before associate any value to it you will get:
Vetor[0]:= 1
Dear Joao,
I do beleive that the SetLength only resize the array, ie: The
Vetor has 3 elements like:
Vetor[0]:= 1
Vetor[1]:= 2
Vetor[2]:= 3
And then eu want the same variable but with only 2 element, then
SetLength(Vetor, 2)
Vetor[0]:= 1
Vetor[1]:= 2
As you can see you
