ERROR Sack Overflow ?!

Thanks. Yes, it is what I want. But I run you code. I did not get the value, wondering whether my computer has problem.

I posted working code. If that doesn't work for you post your full log and the code.
Otherwise go through it line by line and compare and ensure they're exactly the same - they're not.
If you want to make changes for whatever reason, do them one at a time AFTER you've verified the code I posted works as posted.

Not Sure what is going on?!

0) How to a macro variable with another macro variable in it?! 

1) Why cannot delete the macro variable(below)? Is my computer having problem?!

It appears that you deleted the variable and then attempt to delete it three more times. The 'not found' means the variable does not exist in the scope where you are are attempting the %symdel.

0) How to a macro variable with another macro variable in it?!

Provide a completely worked example of what this is supposed to mean. Start with some values, describe the rules and then show the final result.

A "Sack Overflow" is something I would expect to happen in the NFL, especially now that it's playoff time 😉
