Getting started with smalltalk
Installation or Setup
The name Smalltalk usually refers to ANSI Smalltalk or Smalltalk 80 (of which the first is based on). While most implementations are close to the standard, they vary in different aspects (usually referred to as dialects).
Each implementation has it’s own method of installation.
Well known FOSS implementations are:
Squeak (Windows/Linux/Mac OSX)
GNU Smalltalk (Windows/Linux/Mac OSX)
Dolphin Smalltalk Originally commercial, now free open source. (Windows only)
Cuis Smalltalk A Squeak fork with a focus on reducing system complexity.
Commercial Smalltalks include:
VisualWorks/Cincom Smalltalk Free trial available.
VisualAge Smalltalk Originally by IBM, now Instatiations. Free trial available
Smalltalk/x (Free for personal use?)
GemStone/s Free community edition available.

Hello World in Smalltalk
Transcript show: 'Hello World!'.
This will print
Hello World! to the Transcript window in Smalltalk.
Transcript is the class that allows you to print to the Transcript window by sending the message
show: to that object. The colon indicates that this message requires a parameter which is in this case a string. Strings are represented by single quotes and single quotes only since double quotes are reserved for comments in Smalltalk.
