[Error_Push] stores the current error code and error message in a stack and then resets the current error code to 0 and the current error message to empty. The stored error code and error message can later be retrieved using the [Error_Pop] method.

[Error_Push] and [Error_Pop] can be used to maintain the current error code while executing code which might produce an error. For example, a method can use error handling within itself without modifying the error condition for the remainder of code on the page. These methods can also be used to prevent an error condition from propagating into a protect block.
