In theory and error reported by the server can actually contain a
series of errors - althought usually subsequent errors occur as a
result of the first error.

IBO supports this by providing all error codes returned by the server
in the stringlist ErrorCodes, with one error code reported per line.

If you would like more information about how the EIB_ISCError
exceptions are assembled, open IB_Session.pas and look at the
procedure: TIB_SessionBase.HandleException
which is the method that formats the data provided in EIB_ISCError.
