Abstract: After a curve follower lexical symbol recognition system has completed a character examination and found a conflict to exist, a supplementary scan of the character is initiated only for resolving the conflict. The scan traverses across the character at a horizontal and/or vertical level at which there is an identification number of crossovers for the particular conflict. The number of crossovers solves the conflict.

Abstract: JUSTIFICATION OF OVERSTRUCK TEXT Overstruck text is justified by distributing the white space residue at the end of the unjustified line among the interword spaces for justification. The amount of the residue distributed is used to determine a number of overstrike characters which will overstrike the text including these expanded interword spaces. This is accomplished by placing controls in the text stream during editing to delineate the text to be overstruck. Before printing, these controls in the edited data stream are detected to cause the print line to be first justified by expansion of interword spaces and then followed by overstriking with the appropriate number of overstrike characters determined during the justification process.

Abstract: SWITCHING OF PROGRAMMING ROUTINE SUPPORTING STORAGE STACKS A system in which a device or machine is controlled by instructions from a data processor is provided which minimizes main memory storage requirements. An interrupt service routine monitors the input to the processor received from the device in response to control instructions sent by the processor. The interrupt service routine monitors this response for exception conditions. When an exception condition indicating that the device is no longer capable of fully carrying out processor instructions is received by the interrupt service routine, it activates an exception handler routine. A primary memory storage stack normally supports the interrupt service routine. However, upon the activation of the exception handler routine, this primary storage stack is switched to support the exception handler routine, and a secondary stack of significantly lower storage capacity is placed in support of the interrupt service routine which should have lower purported storage requirements during the active period of the exception handler routine. This results in a substantial saving of main processor memory capacity which otherwise would have to be dedicated to the support of the two respective routines.

Abstract: PRINTER SHARING BY PLURALITY OF DISPLAY UNITS IN WORD PROCESSING SYSTEM The present disclosure relates to word processing systems wherein material to be printed is formatted on a display unit having a display, e.g., CRT display and a text formatting processor which formats the display material. The display unit further includes means for controlling a printer to print the formatted text. In the present invention a plurality of such display units share a printer. This is accomplished by having at least one of the display units comprise means for controlling the sharing of the printer by the plurality of display units and each of the other display units communicate with the printer through these printer sharing control means. At least part of this printer sharing control means is contained in the text formatting processor of the primary display unit through which the other display units communicate with the printer.

Abstract: SYSTEM AND PRINTER JUSTIFICATION SYSTEM A system for first justifying a text line according to a system minimum escapement unit, and then rejustifying the line according to a minimum escapement unit for a printer which is to be utilized in printing the line. The first justification of the line is in a normal manner. That is, any residue is divided by the number of word spaces on the line to obtain a quotient and any remainder. The extent of word space expansion is then the value of the quotient plus the remainder until exhausted. Rejustification for the printer being utilized is accomplished by dividing each system justified word space size by the printer minimum escapement unit to obtain a new quotient and remainder. Each system justified word space is then converted to a value including the obtained quotient for each space, and the remainders for all spaces are accumulated for adding to the first word space.
