Andy,
You still didn't understand me.
You are right in your example that it is forbidden to do what you showed but that's not what I meant!!!

I am talking about opposite backslash in the macro which is called 'line continuation sign' (I am new here and didn't have time to learn how to post special characters).
If you want , I can send you some example files which demonstrate the problem , the same ones I sent to Keil because they didn't know the problem.

But , believe me, Keil approved it as a BUG and they said they will correct it in their new version , so I don't see the reason why we are spending time on it.
In summary , there is a bug , and I wanted only notify people about it to save their time( I spent some time to find it). If you still want to uderstand the problem I should send you example, but if not , let's close this issue.
Regards
Yossi
