Oh dear..!
Despite all your tips, Mags, Jazzie n'all...I'm STILL struggling.! I 'ATE this 'New compiler'!!!
Now, I'm even MORE confused when you say NOT Salop..! AND why do I keep thinking of Humphrey
for 4d.? Won't embarrass myself by asking for any more help (hint) but maybe a 'nudge' for 15a, 18a, 23a.????....R. (sigh..!)
