Just started the language but.....

Hiya

I have just started to learn the language but I have no programming
skills. Following the Dolphin tutorial but have a question that I am
sure you'll all get easily.

It says
Let's open a ShellView and play around

w := ShellView new show

When I evaluate it, it says that line 1 : underclared 'w'.

I put |w| at the top and evalutaed it all and it worked.
However, when I went to the next part of the tutorial it opens the
Class Hierarchy and we get the Geometry one but then it says to type

w position: 0@0

It says the same thing as before...undeclared.

As I say, it is an easy question for you but I would appreciate an
answer.

Thank you in advance

Eddie

Try this:

x := Date today.

Position the cursor anywhere on the line (don't highlight anything)
and press CTRL+D. You should see the date. Which version of Dolphin
are you using?

Hi.
I suspect you're attempting to evaluate the expression within the "System
Transcript" window. Try using a Workspace window instead (You can open one
by going to "File->New"). Workspace windows automatically define temporary
variables (such as "w" in your example) as they're encountered. The
Transcript window doesn't provide this behavior.

Hiya

Its version 2.1 and thank you, it worked. I knew it must be something
simple but when you just start out its not the thing that pops into
your mind.

Thanks both of you

Eddie
