This command clears the command queue except for the final command. It is provided to facilitate an atomic way to replace all commands with a single command without introducing a period of no action (the idea is that if you want to replace everything with "ro 5 180 0", you say: "t ro 5 180 0 [NEWLINE] n fm 0", and your quagent will instantly start rotating and forget all prior commands). '''Parameters:''' * This command does not accept any parameters. '''Reports:''' * ''done'' immediately. * ''popped'' if popped by [[po]] before execution. * ''forgotten'' if deleted by [[fa]] or [[fm]]. * ''replaced'' if replaced by a command scheduled with 'r'. * Causes all but one other actions to report ''forgotten''. '''Example:''' * User sends: "n mi 16 0 0 1" * Bot starts moving. * User sends: "t mi 17 0 90 1" * User sends: "t mi 18 0 135 1" * User sends: "t mi 19 0 180 1" * User sends: "n fm 20" * Bot replies "cp fm 20 done" * Bot replies "cp mi 16 forgotten" * Bot replies "cp mi 17 forgotten" * Bot replies "cp mi 18 forgotten" * Bot starts moving backwards (by the instruction "mi 19").
