Abstract
Abstract A system for automatically adjusting text codes and control codes stored in a memory into text blocks having variable formatting parameters and variable line counts. The detection of a code signal causes the system to enter a non-playout adjust mode. The operator is then prompted to enter a line count for the text block to be formatted. After the line count is entered, the system proceeds to adjust in memory the number of lines of text equal to the line count to the predetermined formatting parameters with no external output of the text. An interrupt of the adjust mode occurs upon the detection of any one of a number of predefined special conditions including the end of text, mode-measure codes in memory, special codes (e.g. stop, edit, error, page end), hyphenation requests, forced line overflow, or upon completion of the text block line count. The system presents to the operator visual indicators upon the occurrence of an interrupt sufficient to define the cause of the interrupt and the location in text where the special condition occurred. During the interrupt, the operator may enter information into the system or play out codes from memory, and then enter a code signal that causes the system to continue in the non-playout adjust mode.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
366 words
A system for non-output formatting of text sequences into text blocks, each of said text blocks having a different escapement length than the preceding text block and including at least one text line, comprising: a recirculating memory; a flag code stored in said recirculating memory for defining the addressable point in said recirculating memory immediately following said flag code; input means connected to said recirculating memory for inputting text sequences and format control codes into said recirculating memory, first operator selectable means in said input means for generating a non-output text adjust scan mode signal; second operator selectable means in said input means for entering a range number; display means connected to said input means and said recirculating memory; and control means connected to said recirculating memory, said input means and said display means, and responsive to said non-output text adjust scan mode signal for activating a non-output text adjust mode including means for controlling said display means to display a prompt to the operator to enter a range number representing the number of text lines to be arranged into a text block, means for storing the range number entered, means for detecting the location of said flag code in said recirculating memory, means responsive to the detection of said flag code for decoding format control codes following said flag code in said recirculating memory and storing in a first register a line escapement length defined by said format control codes, and memory scan means, including means for decoding text sequences in said recirculating memory following said flag code and accumulating in a second register escapement values for the text sequences, compare means connected to said first and second registers for comparing the contents thereof, means for generating line ending codes operable to insert a line ending code into said recirculating memory in response to an equal compare from said compare means, means responsive to said means for generating line ending codes for accumulating a count of the number of line ending codes inserted into said recirculating memory, and means for comparing the count of line ending codes to the stored range number operative to deactivate said non-output text adjust mode when the compare is equal.
Claim 2
Independent Claim
366 words
A system for non-output formatting of text sequences into text blocks, each of said text blocks having a different escapement length than the preceding text block and including at least one text line, comprising: a recirculating memory; a flag code stored in said recirculating memory for defining the addressable point in said recirculating memory immediately following said flag code; input means connected to said recirculating memory for inputting text sequences and format control codes into said recirculating memory, first operator selectable means in said input means for generating a non-output text adjust scan mode signal; second operator selectable means in said input means for entering a range number; display means connected to said input means and said recirculating memory; and control means connected to said recirculating memory, said input means and said display means, and responsive to said non-output text adjust scan mode signal for activating a non-output text adjust mode including means for controlling said display means to display a prompt to the operator to enter a range number representing the number of text lines to be arranged into a text block, means for storing the range number entered, means for detecting the location of said flag code in said recirculating memory, means responsive to the detection of said flag code for decoding format control codes following said flag code in said recirculating memory and storing in a first register a line escapement length defined by said format control codes, and memory scan means, including means for decoding text sequences in said recirculating memory following said flag code and accumulating in a second register escapement values for the text sequences, compare means connected to said first and second registers for comparing the contents thereof, means for generating line ending codes operable to insert a line ending code into said recirculating memory in response to an equal compare from said compare means, means responsive to said means for generating line ending codes for accumulating a count of the number of line ending codes inserted into said recirculating memory, and means for comparing the count of line ending codes to the stored range number operative to deactivate said non-output text adjust mode when the compare is equal.
Claim 3
Dependent Claim
57 words
The system of claim 1 wherein said control means further includes means for detecting a memory empty condition, means responsive to the memory empty condition for displaying to the operator a visual indication that the memory is empty, and means for aborting the non-output text adjust mode in response to the detection of a memory empty condition.
Claim 4
Dependent Claim
39 words
The system of claim 1 wherein said control means further includes means responsive to said input means and said means for storing the range number entered for aborting the non-output text adjust mode when no range number is input.
Claim 5
Dependent Claim
39 words
The system of claim 1 wherein said control means further includes means responsive to said means for decoding format control codes for aborting the non-output text adjust mode when no format control codes are present in said recirculating memory.
Claim 6
