Just goes to show what a fresh pair of eyes can spot !
Interestingly, I tried [0-9]+ and it doesn't select anything, whereas
[0-9][0-9]* does. And now I see why VM\? failed, the \ was to escape
the ?, and I overlooked the meaning of ?
Anyway, I settled on '^[0-9][0-9]* VM[?]^M$' (where the ^M is a
return, not two characters) which should be safe - I think in the
past I must have tried $^M which of course doesn't work.
Just proves that most of us still have plenty to learn !
