SBCS Primary w/ DBCS Secondary on V5R3?

["Urbanek, Marty" <Marty_Urbanek@xxxxxxxxxxxx>]

I am under the impression that with V5R3 we are now able to have DBCS secondary 
languages on a system with an SBCS primary language. I even found a reference 
to it in the midrange-l archives, stating that all V5R3 systems are DBCS 
enabled.

However, I am having trouble confirming this in the IBM docs (sales manual, 
Info Center, System Handbook). Can anybody point me to an IBM doc that states 
this?

Thanks,
-Marty
