Atari PILOT is unique in that it added a set of commands for graphics and sound using two-letter commands, GR and SO. The graphics system used turtle graphics, with the string following the GR command containing multiple sub-commands like DRAW and TURN. The syntax for these commands is similar to [WSFN], allowing a series of commands to be repeated by placing them inside parenthesis and putting the number of times to perform it in front.

R:Draw a square in the center of the screen\\
GR:4(DRAW 20; TURN 90)\\
