Filtering lines between an header and a footer in a multirecord file

Hi,

I need help on this topic, please.
I have a multirecord text file that has different sections. I would split every section and send it in an output file step or something similar.
The file has a similar structure:

01 .. data header 1..
02 .. data detail block1..
02 .. data detail block1..
99 .. data footer 1..
01 .. data header 2..
02 .. data detail block2..
02 .. data detail block2..
02 .. data detail block2..
02 .. data detail block2..
99 .. data footer 2..

Headers and footers have the same beginning characters (01 and 99) and all details have always the same beginning characters (02) but fields and data have different sructures

How could split the different blocks in different file output?

Thank you in advance!
Fernando
