ask agentset [commands] ask agent [commands]

The specified agent or agentset runs the given commands. Because agentset members are always read in a random order, when ask is used with an agentset each agent will take its turn in a random order. See Agentsets for more information.

ask turtles [ fd 1 ]
  ;; all turtles move forward one step
ask patches [ set pcolor red ]
  ;; all patches turn red
ask turtle 4 [ rt 90 ]
  ;; only the turtle with id 4 turns right

Note: only the observer can ask all turtles or all patches. This prevents you from inadvertently having all turtles ask all turtles or all patches ask all patches, which is a common mistake to make if you're not careful about which agents will run the code you are writing.

Note: Only the agents that are in the agentset at the time the ask begins run the commands.
