Nawk help searching for multiple lines and multiple searches

I use this command to find a search (Nr of active alarms are) and print one line before and 10 lines after the search keywords.
Code:
nawk 'c-->0;$0~s{if(b)for(c=b+1;c>1;c--)print r[(NR-c+1)%b];print;c=a}b{r[NR%b]=$0}' b=1 a=10 s="Nr of active alarms are:" *.log

However, I would like to know how to tell it to print from the search pattern "Nr of active alarms are" until it find a search pattern "NUMBER"

INPUT FILE:
Code:
A
B
C
D
E....Z

Command: nawk <search B and output from line B until you find D" Basically print B and whatever line between B and D.

OUTPUT:
Code:
B
C
D

Hope that's simple to understand:

You can pipe your command:
Code:
...| sed -n '/pattern1/,/pattern2/p'

If you don't need the last line:
Code:
...| sed -n '/pattern1/,/pattern2/p' | head -n-1
