Hello,

how can I set a dot from after A to before B, then make a global
substitution, within thus set dot, of CC to DD and print the resulting
text?

I.e., if there isn't any CC between A and B, just print what's between
A and B, if there is, change it to DD and print all between A and B.

I have sth like this

/A/+#0;/B/-#0 s/CC/DD/g
p

which works if there *is* the CC, but not if it is not there; then the
s command just resets the dot to an empty set.

Thank you
Ruda
