Abstract

Abstract A method for sequentially obtaining an exact point-to-point correspondence between output and memory. The memory will automatically be rearranged in accordance with line length and/or format determinations. The system is comprised of an electronic dynamic shift register and associated control logic, and an input/output device. Control codes stored in the shift register along with text data codes determine the initial format. This format is altered and at the completion of output the memory will correspond to the output. For example, if a stored line length is 100 units defined by carrier return codes and the measure set on an output printer is 80 units, the memory will not correspond to the printed output. With the system of this invention, during an output operation a carrier return code will be inserted into memory at a point in the line less than 80 units from the line beginning and the carrier return code in memory defining the original 100 unit line will be removed.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 174 words
A method of automatically obtaining an exact point-to-point correspondence between the contents of an electronic storage means and an output format during output from said storage means to a data bus, said method comprising: A. defining by a keyboard means an output format against which said storage contents, being a series in said storage means of data and control codes made up of n bits, are to be sequentially compared; B. sequentially comparing said data and control codes with said output format; and C. altering the arrangement of said data and control codes, upon said comparing, when said storage contends correspond to said output format, by one of the following steps a. writing a new control code over an existing control code in said series to cause said arrangement to correspond to said output format, b. inserting a new control code into said series to cause said arrangement to correspond to said output format, and c. removing an existing control code from said series to cause said arrangement to correspond to said output format.
Claim 2
Independent Claim 174 words
A method of automatically obtaining an exact point-to-point correspondence between the contents of an electronic storage means and an output format during output from said storage means to a data bus, said method comprising: A. defining by a keyboard means an output format against which said storage contents, being a series in said storage means of data and control codes made up of n bits, are to be sequentially compared; B. sequentially comparing said data and control codes with said output format; and C. altering the arrangement of said data and control codes, upon said comparing, when said storage contends correspond to said output format, by one of the following steps a. writing a new control code over an existing control code in said series to cause said arrangement to correspond to said output format, b. inserting a new control code into said series to cause said arrangement to correspond to said output format, and c. removing an existing control code from said series to cause said arrangement to correspond to said output format.
Claim 3
Dependent Claim 16 words
A method according to claim 1 further comprising defining a hot zone within said output format.
