Re: About String

Thanks for all you answer. I m happy to see I did the right way.

Actually not handling exception of the declaring part can be non intuitive at 
first. But I think it is. If you could, you wouldn't know wich data is available 
since you don't know where the exception take place in the declarative part. So 
it's better to handle it externally where you know wich variables are already 
defined. the only matter is that you can handle exception in declarative part of 
a function/procedure. So you have to declare it in subblock and then handle the 
exception. The problem is, if you can't anymore use the string in the body of 
the function, only in the subblock.
