ped with locking mechanism, this will be in the ON position too.
The Terminal Manager is activated with access rights as determined by the SS&C Package.

a) This section describes the principal tasks of each of the Top Level Functions:
- Function Control
- Dialogue Control
- Validation
for each of the types f Terminal Manager:
- VDU - Terminal Manager
- PRINT - Terminal Manager
- PTR - Terminal Manager
- PTP - Terminal Manager
- OCR - Terminal Manager
b) The main functions recognized at this level are:
1) Transaction Handling:
Commnd interpretation, transaction accounting and error response.
Fig. 5.13.1.2.2-1…01…Terminal Package Top Level Breakdown
2) Item Handling:
Operations on items and their control blocks.
3) Table Handling:
Access to tables, system parameters and global
number series.
4) Status, Log, andStatistics Handling:
Collection and maintenance of status log and

via requests/replies.
6) Start, Stop, and Error Handling:
Start up, restart, close down, and local error
handling.
7) Format Handling:
Input, output, and validation of data for terminals.
These functions are mapped onto the Top Level Functions
as follows:
c) VDU - Terminal Manager
The Termial Managers for the various functions
(Supervisor, MDCO, MSO, User) will be different
with respect to commands and detailed functions
and thus inherently prevented from unauthorized
activities. The precise mapping of low level functions
onto Termial Managers and their Top Level Functions
are beyond the scope of this document and will
be defined at a later stage in the design process.
1) Function Control.
The tasks of Function Control are:
- Transaction Handling
- Item Handling
- Table Handling
- Status, Log, and Statistics Handling
- Queueand Request Handling
- Start, Stop, and Error Handling
2) Dialogue Control.
The tasks of Dialogue Control are:
- Format Input/Output and Status display.
3) Validation.
The tasks of validation are:
- Format Validation and Cnversion.
d) PRINT - Terminal Manager.
The Terminal Manager for print-out controls slow
- and medium-speed printers.
1) Function Control.
The tasks of Function Control are:
- Table Handling
- Queue and Request Handling
- Strt, Stop, and Error Handling
2) Dialogue Control.
The tasks of Dialogue Control are:
- Format output.
3) Validation.
- N/A.
e) PTR - Terminal Manager.
The Terminal Manager for paper tape input controls
stand alone PTR and tleprinters used as PTR device.
