Executes this
Command
.Executes this
Command
. Called by NetLogo when thisCommand
is called at run-time.- args

Argument
s that were passed to the command. (May be aReporter
or a constant.) To evaluate arguments, use the typesafe methods in theArgument
interface.- context
the current
Context
allows access to NetLogo internal methods
