First steps

Once you have downloaded a binary package or built from source, you can start Factor as follows:

• Mac OS X: Double-click Factor.app or run open Factor.app in a Terminal to start the UI; run ./factor in the Terminal to start a command-line listener
• Windows: Double-click factor.exe, or run .\factor.com in a command prompt, to start the Factor UI
• Unix: Run ./factor in a shell to start the Factor UI if $DISPLAY is set, otherwise start a command line listener

For more details, see Running Factor.

Taking the plunge

• Start by reading the Factor cookbook and the "Your First Program" tutorial. These can either be read online, or in the UI.
• Read an unofficial Factor tutorial.
• Although it is an academic article, Factor: A Dynamic Stack-based Programming Language is very helpful for anyone new to Factor or even to stack-based programming languages.
• Look at some Examples.
