    Hi all.

    There are two string:

    Str1:STRING;
    Str2:string;

    When we do:

    Str1:=str2

    Str2 is copied on str1, or str2 points to the str2.

    Anyone knows?

    I don't understand what is the meaning of "or str2 points to the str2".

    When you write :
    Str2:=Str1;
    Str1 is copied into Str2.
    For example if str1 is 'Hello', Str2 will be 'Hello' too.
    := is an affectation, it is to say that the right part is tranfered in the left part.
    You can easily test it with siulation.

    As JAPIB says

    When you write :
    Str2:=Str1;
    Str1 is copied into Str2

    Thanks guys. I test it and you are true. After the equal, if the first string is modified the second does not change.

    Comming from Java and c the sintaxis is a little bit diferent
