substring of a variable

I'm working in:

#!/bin/ksh

My question:

I have a variable latest_bus_date, which in in the format YYYYMMDD. I would like to create a new variable that is in the format of MMDDYY using the data stored in latest_bus_date.

$latest_bus_date='20020304'
The new variable should have: 030402

Any ideas?

Thanks,

This is done in /bin/ksh on Dynix/ptx 4.4.8:

This isn't the prettiest command ever, but it works from what I can tell...

new_date="`echo $latest_bus_date |cut -c5-6``echo $latest_bus_date |cut -c7-8``echo $latest_bus_date |
cut -c3-4`"

echo $new_date

Thank you - it works!
