Some doubts in pascal language..

[Parcel]

Im advancing in pascal but i don't know some things like...

- how use "for in" loops

- a const of arrays

- is there a way to do something like ->
[pascal]var uuu : array [0..1] of integer;
begin
uuu := ((1),(2));[/pascal]

[pascal]
const
uuu : array[0..1] of integer = (1,2);
[/pascal]
