Example · generated

Form 1, the short one

DO  Print(OpenPreferences("assets/data.dat"))  Sync()LOOP

Form 3, with every argument

DO  Print(OpenPreferences("assets/data.dat", 1, 1))  Sync()LOOP

OpenPreferences is called and its answer is printed every frame. The DO … LOOP is not decoration: a classic BASIC program ends the moment it runs out of lines, and Sync() is what draws the frame.
