I have return files from a process that has then original input record followed on the next line by a response record..either AA,........... for accepted or EE,.......... for errored.

i.e

11,new,123
AA,accepted
12,exist,443
EE,rejected
13,old,223
AA,accepted

I want to write a small script that will return the row and it's response to a separate file.

I.e. I tell the script I want the records that start 11 and their responses and I get the first two lines above. I can do the pattern matching etc to get the first line - but I am having trouble getting the second line to come back too.
