John, thanks - that's interesting stoff. As it turns out my Word program yesterday decided to crap itself.

Are you game enough to try some experiments in Word (of which I only know the basics) to try some Whistle TAB based on your knowledge? If you're a whistle player that's fine, but otherwise you can assign any combinations of X, O, + (for the second octave) and maybe - (for 'alf covered 'oles).

I have no idea whether this can be done in Word - with or without macros because in my working life I only ever used it for fairly straight business correspondence. You only need to try a few symbols in upper and lower case, eg C,D,c,d in order to prove the concept.

Regards, John
