Hello  World!
I'm talking the code style in Alice3.
Alice has two ways of showing code,
The  Alice mode and the Java mode, Alice is the default,
but all of the lessons in zebra0
are going to use the Java code style.
If we declare a variable,
and I pick the type
and I see DecimalNumber, WholeNumber, Boolean and TextString,
I'm in the wrong mode!
Go to Window, preferences, programming language, select Java.
Now, when we declare a variable
you have a choice of Double, Integer, Boolean and String.
And that is what we want to see.
So we could have greeting
And  set custom text string of Hello World
Say  OK, OK,
and this is the way you want it to look.
And that's it, but that's very important!
