Who says that programming in smalltalk is different from others ?
You can write smalltalk with a simple Texteditor. However.
I have written a simple program here , with smalltalk V 2.0 , 16bit
1. The programs name is : Prozentrechnung
Only one class is the programm. Only one method is the program.
ok. there could be more interdependencies such like "subroutines"
not important for understanding
2. The method "startUpApplication" from the class "Notification"
is responsible for opening the own programm. ( itself a class
uhhhhhhhhh )
So the only thing you have to do is to tell the
strartUpApplication method
the program Name. here Prozentrechnung new open. thats all
3. Now you have to type a Method named open. for Notification
to READ.
4. In most cases is is self and then the startmethod of your
own program.
Here in my program the Promter is asking first with a simple window
to INPUT DATA !
Very simple and easy.
I dont care about the endless procedures in other smalltalk
implementations
but one thing is shure . " i have opened that fucking thing here in
smalltalk ! "

Prozentrechnung new open.
