awk and sort for a chain of characters in a file

Hi all,

I have a file with a lot of records similar to this:

023456AB2543999210709
022656AB2543999210409
024556AB2543999200709
024556AB2543999200909

I want to sort this file by using two parts of each record, for example: positions 3 to 4 like one field ascending and
positions 16 to 19 like other field descending.

The result:
022656AB2543999210409
023456AB2543999210709
024556AB2543999200909
024556AB2543999200709

how can i do it? It is possible using awk?

Thanks.

Does it have to be awk? Why not sort?

Code:

cat yourfile | sort -k1.3,1.4n -k1.16,1.19r
