Any attempt/idea/thought from your side? Did you consider the links at the bottom of this page?

try:
Code:
awk 'a[s1] && a[s2]; {a[$0]=$0}' s1="AAA" s2="BBB" infile

Anyway, one option would be
Code:
awk 'P; /AAA/ && !P {getline; if(/BBB/) P=1}' file
CCC
ZZZ

Code:
awk 'a&&b ; /AAA/ {a=1} /BBB/&&a {b=1}' file

The extra condition&&a means that BBB must come after AAA.
