Abstract
Abstract In a text processor including a communications facility, different tasks, such as typing tasks and communications tasks are entered into the machine from different program diskettes. As each is so entered, in view of the fact that main memory space is limited, it overlays control data in the main memory relating to the previous task. In a communications session, the operator has to build a queue of documents for sending under the control of communications foreground control (CFC) and communications background control (CBC) blocks in the main memory. If the operator is required to terminate this task before its completion, his queue data is lost as it is overlaid by control data relating to a new task that is entered, so on return to the communications task, he has to start from the beginning. In order to enable him to exit the communications task without losing the queue data, an arrangement is employed whereby this data can be entered on to the communications program diskette prior to termination of a communications session.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
112 words
A text processor system including a main memory, communications means for transmitting messages through a communications line and a storage unit for transferring data between storage elements mountable therein and the main memory, said data including a communications control program contained on a communications control storage element and message data contained on a further storage element, and including means for developing, in the main memory, data defining a queue of messages to be communicated from the system under the control of the communications control program and means responsive to interruption of the queue data development to cause transfer of the queue data from the main memory to the communications control storage element.
Claim 2
Dependent Claim
112 words
A text processor system including a main memory, communications means for transmitting messages through a communications line and a storage unit for transferring data between storage elements mountable therein and the main memory, said data including a communications control program contained on a communications control storage element and message data contained on a further storage element, and including means for developing, in the main memory, data defining a queue of messages to be communicated from the system under the control of the communications control program and means responsive to interruption of the queue data development to cause transfer of the queue data from the main memory to the communications control storage element.
Claim 3
Dependent Claim
45 words
A text processor system according to claim 1 including means operative on a recall of a communications task subsequent to its interruption to direct the transferred queue data together with the communications control program from the communications control storage element back into the main memory.
Claim 4
Dependent Claim
53 words
A text processor system according to claim 1 adapted to perform separate tasks, including communications tasks, under the control of task programs, each of which is stored on an individual storage element and each of which, when read from the storage element to the main memory, overwrites the task program previously written therein.
Claim 5
Dependent Claim
51 words
A text processing system according to claim 1 including means for instructing an operator, by way of a display device, to transfer said queue data upon interruption of the queue data development and to insert said communications control storage element into said data storage unit if it is not mounted therein.
Claim 6
Dependent Claim
53 words
A text processor system according to claim 2 adapted to perform separate tasks, including communications tasks, under the control of task programs, each of which is stored on an individual storage element and each of which, when read from the storage element to the main memory, overwrites the task program previously written therein.
Claim 7
Dependent Claim
51 words
A text processing system according to claim 2 including means for instructing an operator, by way of a display device, to transfer said queue data upon interruption of the queue data development and to insert said communications control storage element into said data storage unit if it is not mounted therein.
Claim 8
Dependent Claim
51 words
A text processing system according to claim 3 including means for instructing an operator, by way of a display device, to transfer said queue data upon interruption of the queue data development and to insert said communications control storage element into said data storage unit if it is not mounted therein.
Claim 9
Dependent Claim
104 words
A text processing system adapted to perform multiple tasks each under the control of control data contained in an individual discrete storage element mountable into a storage unit from which the control data is transferred to a main memory device, thereby overwriting control data already therein, including means for initiating a communications task wherein data representing a queue of messages to be transmitted from the system is assembled, and means responsive to an interruption of a communications task prior to its completion to transfer said data representing the queue of messages to the discrete storage element containing the control data for the communications task.
Claim 10
Dependent Claim
104 words
A text processing system adapted to perform multiple tasks each under the control of control data contained in an individual discrete storage element mountable into a storage unit from which the control data is transferred to a main memory device, thereby overwriting control data already therein, including means for initiating a communications task wherein data representing a queue of messages to be transmitted from the system is assembled, and means responsive to an interruption of a communications task prior to its completion to transfer said data representing the queue of messages to the discrete storage element containing the control data for the communications task.
