ACSLogo for OSX Version 1.6

ACSLogo is a Logo Interpreter for Mac OS X.

Logo is a popular language used to teach simple programming by guiding the progress of a ‘turtle’ which moves around a graphics screen.

Despite Logo’s simplicity, complex pictures can be constructed, as the screenshot shows.

A new version is available — 1.6 (October 2019). This version is required for macOS Catalina. You can find out more about the program and download it for free from here.
