Shell Programming and Scripting

Hi all;

I'm stuck with this simple awk script,i need to group the lines which the position of 28 length 3 that contains "688" into 1 group and other than "688" into another group. My problem is the script only read other than "688" and ignores the lines which contains "688".

The file look like this:
040171011140820070000000009650244002933170003000000075272

1H912279980109 01082007000688djjdfieuireurireiro

I used this script to group the lines:
After execute the script,the output shown:
040171011140820070000000009650244002933170003000000075272

can anyone help me to figure out?tq in advance

The value of j isn't set before the if statements.
Can you place your code within code tags to improve readability?
