Any text editor can be used to edit plotscripting script files, as long as it saves in plain-text format, using either Unix or DOS line endings (beware that some editors on Macs use Mac line endings by default). HSS files are just .txt files with an .hss extension. Although using a .hss extension is slightly encouraged, .txt is fine too.
- Notepad++ A general-purpose programmer's text editor for Windows that is great for plotscripting too!
