The means exists for virtual code applications to have run time error
messages written to standard error on their behalf by
avram. Any error messages not documented here originate with an
application and should be documented by it.
Most error messages originating from avram are prefaced by the
application name (i.e., the name of the file containing the virtual
machine code), but will be prefaced by avram: if the error is
caused by a problem loading this file itself. Error messages originating
from virtual code applications are the responsibility of their
respective authors and might not be prefaced by the application name.
The run time errors not specifically raised by the application can be classified as internal errors, i/o errors, overflow errors, file format errors, application programming errors, and configuration related errors.
Some error messages include a code number. The number identifies the specific point in the source code where the condition was detected, for the benefit of the person maintaining it.
