TELL
Syntax TELL number 
TELL name 
TELL list 
Explanation TELL activates the objects that respond to turtle commands. Objects may either be turtles, bitmaps or controls. A single number as an argument to TELL activates that single turtle. A list of numbers or  names activates all the turtles, bitmaps or controls named in the list.

Use TELLALL 0 (TURTLES - 1) to activate all available turtles.

TELLEVEN and TELLODD also activate a range of turtles.

Before turtles may be activated, they must be defined by the SETTURTLES command. The default number of turtles available when Logo starts is 16 (turtle.0 through turtle.15).

After startup or after execution of a SETTURTLES command, turtle 0 becomes the active turtle.

See also SETTURTLENAMEASK, EACH, TURTLES, and WHO.

Examples This procedure tells the turtles to set their color to the same value as their turtle number. They then move apart in different directions.
