Splitting the file based on two fields - Fixed length file

Hi ,
I am having a scenario where I need to split the file based on two field values. The file is a fixed length file.
ex:
Code:
AA0998703000000000000190510095350019500010005101980301      
K 0998703000000000000190510095351019500020005101480         
CC0338703368396368396190510114449019600010005101980301      
L 03387033683963683961905101144500196000200051012803        
I O553203000000000000190510120433019700010005101980301

Split based on 4th position to 4 char (9987) and 21st to 6 char(190510)

So, in the above example there will be 3 files generated.
Code:
9987_190510.txt
3387_190510.txt
5532_190510.txt

I tried with the below command,
Code:
awk '{ F=substr($0,4,4)".txt"; print $0 >> F; close(F) }' filename

But it splits only on the first set, I need to do it with the combination of both sub strings.

Please wrap all code, files, input & output/errors in CODE tags.
It makes it easier to read and preserves white space which is important for indenting or fixed-width data.
