Hi all,
I have a "recipe" which looks like this

19C82-B
12
G
1B
H
...
H4


100C9-B
6
G
2B
H
12

What I would like to do is lookup 19C82-B return the rows until the new pattern 100C9-B starts. Patterns are as follow either 1,2,3 characters followed by a C,D, or R and then some number of characters after. Any thoughts?
