Alphanumeric Error Messages
The NSARPA/1000 error messages described in this section are categorized as follows:
DSubsystem Error Messages. These error messages consist of four fields of information: a subsystem prefix, a numeric error code, a numeric error qualifier code, and an ASCII message. For example, the error message DS-1(0) – PROGRAM NOT FOUND contains the subsystem prefix DS, the error code 1, the error qualifier code 0, and the ASCII message PROGRAM NOT FOUND. Subsystem errors may be returned to the current log device through REMAT, or in the err parameter of PTOP, RFA and certain utility calls. They may also be returned in the A and Bregisters after a DEXEC or utility call. When a subsystem error is encountered by REMAT, it is returned in its full alphanumeric form to the current log device. When such an error is encountered by a PTOP, RFA or a utility call, only the error code is returned in the err parameter. The A and Bregisters return the subsystem prefix in the Aregister and the error code in the Bregister.
DSystem Console Error Messages. These error messages are returned to system LU 1 and are the result of •unexpected" as well as program download errors.
DMiscellaneous Alphanumeric Error Messages. These error messages are also returned to the current log device. They have no numeric equivalent and thus are not returned to any NSARPA/1000 call.
