Initial error context level
In the non-ADAM, stand-alone, version of the Error System the initial error
context level is set to one.
Thus, before any calls to ERR_MARK have been made, calls to ERR_LEVEL will
return a value of one and any error reports made at this level to be delivered
immediately to the user.
However, for ADAM applications, error reporting is deferred before
the user's application code is called.
Thus calls to ERR_LEVEL made before any calls to ERR_MARK will return a
value of two to the application,
Any remaining error reports are delivered to the user by the ``fixed-part''
of the ADAM application after execution of
the user's application code.
