What have you done to find out?
perldoc -f sort perldoc -q "sort an array"
I think you also need to read up on data structures:
perldoc perldsc
Gunnar, It works! I can't express enough my gratitude for your help and patience.
I apologize for having trouble you this far.
Actually I did some reading on array sorting. However, I admit I didn't do enough reading especially on the topic of "hash reference".
Gratefuly yours, Edward WIJAYA SINGAPORE
