Example · generated

Form 1, the short one

regularExpression = CreateRegularExpression(1, "value")DO  Sync()LOOP

Form 2, with every argument

regularExpression = CreateRegularExpression(1, "value", 1)DO  Sync()LOOP

CreateRegularExpression 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.
