Hi All

I want to understand what's the difference between Z/OS, OS/390 at developer's level ? I know that Z/OS is 64 bit system so it will reduce paging and improve performance ...but do we have to code something in our programs/jcl (from os/390) to make them compatible to z/os ?

at design level what all parameters we can adjust to make use of z/os capabilities ? Also if anyone could point me to a document or website where i can get this information ..

any help will be greatly appreciated ?
