Some programs run continuously, while some are scheduled.Diagnostic programs are resident or non-resident software programs.Resident programs, such as the Error Monitor and Resident TrunkDiagnostic, are always present in system memory. Non-resident programs,such as the Input/Output Diagnostic and Core Equipment Diagnostic, areused as Midnight and Background Routines or for interactive diagnostics.Non-resident programs are loaded from the system disk and are run asscheduled or upon request.See the Software Input/Output: Maintenance (553-3001-511) and SoftwareInput/Output: System Messages (553-3001-411) for detailed information onall diagnostic programs.OverlaysNon-resident programs are also called overlays or loads. They are identifiedby a title and a number preceded by the mnemonic for load (for example,Trunk Diagnostic — LD 36).MG 1000TThe MG 1000T platform supports the same overlay commands andassociated TN format (c u) as the CS 1000S system.CS 1000EThe CS 1000E Core Call Server and MG 1000Es support the overlaycommands and TN format (l s c u) associated with Large Systems.The Call Server also supports additional maintenance functions in Overlays30, 31, 32, 34, 36, 38, 45, 46, 77, and 80 in the same manner as CS 1000Ssystems, while maintaining the l s c u TN format.
