I have built on Duncans survex example to develop NotePad++ user defined language styles for Therion. The simple one is a bit trivial, but is effective in making Therion data files easy to understand when editing with NotePadd++. The other is comprehensive but rather busy and colourful. It shows up the limitations of the NotePad++ styles format. Simplifying it would perhaps be an improvement. Still someone might find them useful. An improvement would be to have slightly different styles for *.th, *.th2, *.thc (my version of thconfig*) files. But three files are harder to keep consistent. Bruce
