I'm interested in how the compiler optimizes. In the code below, is (1)
optimized to (2) when the code is compiled or does it calcuate Size div
10 - 1 each iteration? Furthermore - where can I read more about
compiler optimization?

1)

for Iterator := 0 to Size div 10 - 1 do

2)

Size := Size div 10;

for Iteratopr := 0 to Size - 1 do
