Hi Paul I was a bit shocked to discover you had removed the standard Lua 5.1 Interpreter :( Could you point me at some instructions as to how I add that back in please ? A second more wacky question for you. How easy or difficult would it be to modify ZBS so that its syntax colour highlighting was for a different language other than Lua ? I am guessing this might be hidden away inside the Scintilla edit component you are using, so therefore would be very awkward to change ? Thanks for your time, and the excellent ZBS !! Geoff
