[Help-smalltalk] Tutorial Bug

[Edward Grabczewski]

I'm a complete newbie to Smalltalk and so I need a good Tutorial. On the face of it the Web site manual seems okay to *look* at but in fact misses some crutical info that stops me dead in my track. Heres the problem.

 

In the Readme and online Tutoral (the second or third exercise from the start) we are told to enter the following commands. But they don't work ...

 

 

It says I shoud type:

x := Array new: 20 !

which returns the message:
assignment to undeclared variable x

Then when I'm told to type:

(x at: 1) printNl !

which *should* return
nil

it in fact returns the error message:
undefined variable x referenced

So what's missing?
