Thank you all for your suggestions! I tried to get along with Squeak. Very different GUI as i never had any contact with such a kind of program. Could some of you guide me shortly which kind of tool or window i have to open to get a similar text window like in Kyma to quickly evaluate some codings? Thank you very much for helping me!

A browser is your access to the source code of the system.
A workspace is a general text editing area in which you can select (highlight) snippets of code and execute them. You have three options for execution:
do it, which will evaluate the code 'silently', that is, will not show the resulting object
print it, which will evaluate the code and show the result. Note that the result is the 'printString' of the object returned by the final expression. Typically you specify the return value using the cara ( ^ ). So if you have a Person object with firstName and lastName instance variables, create a new instance (named myPerson for this example), set the firstName and lastName instance variables, and want to see the result, you would make your final statement
^myPerson firstName, ' ', myPerson lastName
inspect it, which opens an object inspector on the object returned by the last expression in the code you evaluate. So if your code ended with
myPerson
or ^myPerson
inspect it would open an inspector on the person instance held by the myPerson variable.
This allows you to look at the "guts" of the object by seeing the names and values of the instance variables of the object.
The Transcript can be used as the equivalent of standard i/o, so you might have your code do something like
Transcript show: myPerson firstName, ' ', myPerson lastName
On evaluation the resulting string will be displayed in the Transcript window.
If you use 'do it', that's all. If you use 'show it', the returned value will be
aTranscriptStream ''
which is the print representation of the Transcript object.
If you use inspect it, you get an object inspector on the Transcript object.

Hope this helps!
