Error table limits
The error table can contain up to 32 error messages, normally reported at
different levels within the hierarchy of a structured program.
If an attempt is made to defer the reporting of more than 32 error messages,
then the last reported error message will be replaced by the message:
!! Error message stack overflow (EMS fault).
There are up to 256 context levels available in the Error System, the
initial (base-level) error context level being 1.
The current error context level may be inquired using a call to ERR_LEVEL.
If an attempt is made to mark a context level beyond 256, the error message:
!! Error context stack overflow (EMS fault).
is placed on the error stack at context level 256 and any subsequent error
reports will be placed at context level 256.
A bug report should be made if either of the ``EMS fault'' error messages are
reported from software.
