In an editor that provides for the creation and modification of documents, it is common to provide various editing functions, such as insert, delete and move. However, when a letter or other document has been marked up with many paragraph moves, the editing process becomes tedious since each paragraph to be moved must be individually marked by a block cursor and then the new location of the paragraph pointed to. This process is quick and convenient for moving one or perhaps two paragraphs, but when multiple paragraphs must be moved, the user needs a way to automatically rearrange the paragraphs easily. The solution to this problem is to provide the user with a sort function which is outlined.

A PROM (programmable read-only memory)-based table-look-up bus arbitrator arbitrates a common resource between multiple requesters. Programmability of the PROM permits easy changing of the priority scheme, in contrast with current hard-wired arbitrators.

This simple window system can be used most ASCII terminals. Arbitrary rectangular regions of the screen may be defined as windows. Output directed to a window will be confined to that region of the screen. By assigning a different window to each task, tasks may conveniently share the screen without worrying about each other. The system also manages access to the keyboard so that multiple tasks may simultaneously request input without confusion.

The authors introduce estimates for the distribution of linked jobs in an inhomogeneous computer system with strict separation of memory. The characteristics of channel operation are obtained, and I/O planning is effected in relation to the systems time of the processor and channel. A job-dispatching algorithm is developed, with allowance for linking and transmission of information between processors.

This article describes an error diffusion algorithm for a display system of the color look-up table type, which can suppress error cumulation during propagation of quantization error. Error diffusion is performed by feedback from the output of the decode table to the input of the encode table through an error diffusion means. This feedback is switched to ON or OFF responsive to the level of the remaining quantization error.

For the microcomputer development system MRES 1520 a decision table-oriented software development system was created. It represents a computer-aided means for design, programming, correction, and test of K 1520 computer programs. With this, the software design for the K 1520 computer family is carried out in a way near to the application problem. The use of this software design system is demonstrated by means of the control for a feed system and a car.

A processing method is described for the document image composed of characters, graphics and photographs, extracting those regions by the following procedures. (1) Two-dimensional Fourier transformation is performed for the entire image, the angle of the character lines is corrected utilizing the peak coordinate of the transform result, and the period of the character lines is calculated. (2) Based on the real and imaginary parts of the transform result, the coordinates for the characters are calculated. (3) The two-dimensional Fourier transformation is performed for the subpictures determined by the character periods. An experiment was performed for the image (journal article and patent document) composed of graphics and photographs, and it is verified that the method can extract the regions with sufficient accuracy.

A method is described which permits the operator of an interactive processing system to vary the size of a table by providing attributes for the number of rows and columns. Typical spreadsheet applications define a spreadsheet to be of a maximum fixed number of cells, e. g. , 1000 by 1000 cells. In order to bring a portion of the spreadsheet into a composite document where objects of different types may reside on the same page, the operator must first electronically cut the data out of the spreadsheet and electronically paste the data into the document. If the operator's intention was to only use a 4 by 5 table for the data, the operator could not allocate only those needed cells. The new method provides attributes of the table which allow the operator to define how big the table is when created in-line within the document.

A relation chart is a graphic representation of a value or of the type of a structured data variable in form of a semantic network of data elements. Relations charts cannot only be used to represent schemes in data base systems;the paper rather emphasizes the use of relation charts outside of data base applications. This is illustrated by the example of a graphics editor. Relations charts are based on concepts of cognition theory object, attribute and relation. The graphic symbols are related to the mathematical view of sets and relations.
