Abstract
Abstract The disclosure relates to an improvement to an information processing system for conducting data processing operations wherein the processing relates to the value of the information and conducting text processing operations wherein the processing affects only the format of information. The improvement provides the combination of means for initiating a data processing session in said system, means for switching to a text processing session before the completion of the data processing session, means for storing the status of the non-completed data processing session during the text processing session, and means for switching back from the text processing session to the non-completed data processing session.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
107 words
In an information processing system for conducting data processing operations wherein the processing relates to the value of the information and conducting text processing operations wherein the processing relates only to the format of the information, the improvement comprising means for initiating a data processing session in said system, means for initiating a text processing session in said system, means for switching to said text processing session before the completion of said data processing session, means for storing the status of said non-completed data processing session during said text processing session, and means for switching back from said text processing session to said non-completed data processing session.
Claim 2
Dependent Claim
107 words
In an information processing system for conducting data processing operations wherein the processing relates to the value of the information and conducting text processing operations wherein the processing relates only to the format of the information, the improvement comprising means for initiating a data processing session in said system, means for initiating a text processing session in said system, means for switching to said text processing session before the completion of said data processing session, means for storing the status of said non-completed data processing session during said text processing session, and means for switching back from said text processing session to said non-completed data processing session.
Claim 3
Dependent Claim
80 words
The information processing system of claim 1 wherein said system comprises a text processor having an interactive display terminal for conducting said text processing operations, a data processor for conducting said data processing operations, means activated during said data processing sessions for operating said text processor as an emulation of an interactive display terminal, and means for connecting said emulated display terminal to said data processor, whereby said emulated display terminal functions as a display terminal for said data processor.
Claim 4
Dependent Claim
94 words
The information processing system of claim 2 wherein said text processor further comprises a data entry keyboard, means for storing a plurality of different character sets, each set corresponding to said keyboard, means responsive to said switching to a data processing session for selecting a first character set and responsive to said switching to a text processing session for selecting a different character set and means for switching from said first selected character set to the different character set in response to said switching from said data processing session to said text processing session.
Claim 5
Dependent Claim
47 words
The information processing system of claim 2 wherein said text processor further includes means for conducting text processing operations as background tasks during data processing sessions, and wherein said means for switching to said text processing sessions switch to text processing sessions related to said background tasks.
Claim 6
Dependent Claim
47 words
The information processing system of claim 2 wherein said data processor further includes means for conducting data processing operations as background tasks during text processing sessions, and wherein said means for switching to said data processing sessions switch to data processing sessions related to said background tasks.
Claim 7
Dependent Claim
90 words
The information processing system of claim 1 further comprising a data entry keyboard, means for storing a plurality of different character sets, each set corresponding to said keyboard, means responsive to said switching to a data processing session for selecting a first character set and responsive to said switching to a text processing session for selecting a different character set, and means for switching from said first selected character set to the different character set in response to said switching from said data processing session to said text processing session.
Claim 8
Dependent Claim
43 words
The information processing system of claim 1 further comprising means for conducting text processing operations as background tasks during data processing sessions, and wherein said means for switching to said text processing sessions switch to text processing sessions related to said background tasks.
Claim 9
Dependent Claim
43 words
The information processing system of claim 1 further including means for conducting data processing operations as background tasks during text processing sessions, and wherein said means for switching to said data processing sessions switch to data processing sessions related to said background tasks.
Claim 10
Dependent Claim
100 words
In an information processing method for conducting data processing operations wherein the processing relates to the value of the information and conducting text processing operations wherein the processing relates only to the format of the information, the improvement comprising the steps of initiating a data processing session in said system, initiating a text processing session in said system, switching to said text processing session before the completion of said data processing session, storing the status of said non-completed data processing session during said text processing session, and switching back from said text processing session to said non-completed data processing session.
Claim 11
Dependent Claim
100 words
In an information processing method for conducting data processing operations wherein the processing relates to the value of the information and conducting text processing operations wherein the processing relates only to the format of the information, the improvement comprising the steps of initiating a data processing session in said system, initiating a text processing session in said system, switching to said text processing session before the completion of said data processing session, storing the status of said non-completed data processing session during said text processing session, and switching back from said text processing session to said non-completed data processing session.
Claim 12
Dependent Claim
23 words
The information processing method of claim 9 comprising the further step of conducting text processing operations as background tasks during data processing sessions.
Claim 13
Dependent Claim
29 words
The information processing method of claim 10 wherein the step of switching to a text processing session switches to text processing session relating to one of said background tasks.
