Turtle Command

pd, pendown

Turtles put down their "pens," meaning that they draw when they move, leaving a trail behind them. The color of the pen is that of the turtle. Note: Only fd and bk will draw a line.

Examples:

if pc = blue [pd] commands the caller to put its pen down and leave a trail behind it if the patch it is on is blue.
