Where to perform UCCHECK etc in a UNICODE System or NonUNicode System

Hi ,

Inorder to find out Our system is Unicode System or not , generally we can do that by ...... System --> Status .

Here in my case My Sytem is not a Unicode System.

But My project is a Combined Upgrade and Unicode . We are doing the UCCHECK for Unicode Errors.

My doubt is We have to perform UCCHECK etc in a UNICODE System or in a NonUNicode System ?

Thanks in advance

Sriram..
