Thank you. But, what about if any r real macro invocation problems exist in my rest of the code.

How do you distinguish between this example and 'real' macro invocation problems?

I think that's my question too. Here in the log I can see it &XX resolved to '%T ' that's why I thought its not a issue. Correct me if I am wrong.

The %UPCASE function will remove macro quoting. If you want to keep the % sign quoted, change to %QUPCASE:

1    %let endlike= %nrstr(%t);
2    %let xx= %qupcase(&endlike);
3
4    %put &xx &endlike;
%T %t
