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.
