'CONTINUE' keyword in Oracle 10g PL/SQL

In C++: Is it possible to have a named enum be continued in a different file?
For example: Base class header file has: enum FOO { FOO_A, FOO_B, FOO_C, FOO_USERSTART }; Then the derived class has: enum FOO { FOO_USERA=FOO_USERSTART FOO_USERB, FOO_USERC }; Just to be clear on my usage it is for having an event handler where the base class has events and then derived classes can add events. The derived classes...

Looping best practices
I have a very large loop that loops a 1000 rows. I exit the loop if magic value 1 is found. If magic value 1 is not found but magic value 2 is found then the loop needs to skip to the beginning. Right now I am using a switch, some ifs and a goto. I have read that goto is not the best way. Is there a better way to make this work? ...

Why should I avoid using Java Label Statements?
Everywhere across the internet people say that you should avoid using label statements in java. However, I find them very useful in some cases, namely nested loops.

When an unexpected exception occurs in your program (in the debugger). Sometimes you just want to skip it since killing the program at that point is more harmful than continuing. Or you just want to continue since you were more interested in another error/bug Is there an option/compilerflag/secretswitch to enable this? I understand exc...
