GNU poke is, first and foremost, intended to be used as an interactive editor, either directly on the command line or using a graphical user interface built on it. However, since its conception poke was intended to also provide a suitable and useful foundation on which other programs, the so-called binary utilities, could be written. This chapter shows how to write Poke scripts and programs.
