Line 1:
Line 1: − + − In progress.+ − * The Start action is the main procedure+ − − * The Setup action defines and initializes variables, and sets the orientation of the turtle − − * The Tape action writes the initial tape. User can change values in repeat statements to change arguments. − − * The Program action followed by the stack1 action writes the program table line by line. This is divided in two so that the segments fit in the Turtle Art workspace − − * The Execute action carries out the next program step until the halt state is reached − − * The ToTape action Move turtle to current cell on tape − − * The ToProgram action Move Turtle to beginning of current program row to execute − − * The WriteCell action Write current color to current cell, and move to next cell − − * The WriteSymbol action Write current color in cell without moving − − * The ReadPixel action Read RGB values of pixel to stack, pop to variables − − * The SetValue action Find value of cell symbol from RGB numbers − − * The SetMove action Read next Move direction from program table − − * The SetSymbol action Read next Symbol to write from program table − − * The SetState action Read next State from program table − − * The NewCell action Move left or right and set cell number of new location − − * The Log action Write Step number, Symbol, Move, State, Cell number on new log line in black, saving and restoring
