Abstract

The drawing shows three tables on one page. The left table is composed in flush right format. The middle table is composed in center format. The right table is composed in leader format. The bottom list shows in proper sequence the codes on a record necessary to cause the tables shown to be composed using this system. Control information needed to compose each table is stored continuously during an operation on a manuscript. Tabulate codes in the text data are automatically recognized to cause computations based upon the control information for the next table.

Automatic Composition of Tables

The drawing shows three tables on one page. The left table is composed in flush right format. The middle table is composed in center format. The right table is composed in leader format. The bottom list shows in proper sequence the codes on a record necessary to cause the tables shown to be composed using this system. Control information needed to compose each table is stored continuously during an operation on a manuscript. Tabulate codes in the text data are automatically recognized to cause computations based upon the control information for the next table.

Computers for text composition using modern special and general purpose data processing techniques are well-known and essentially readily available. Such computers can have the ability to handle various formats, such as a flush left, flush right, leader, and center. Such a computer is used here in combination with added structures.

Devices are provided to store the basic information with regard to tables. The codes into the computer to effectuate this are prefix t x1, y1, x2, y2, ...x20, y20... The prefix code indicates that instructions are to follow. The t code is then recognizable as indicating that the instructions are for a tabular mode. The x codes are single codes in the standard machine code for the various formats. The x1 code, for example, can be a 1 code which is recognizable as a leader instruction. The x20 code can be a c code which is recognizable as a center instruction. The y codes give unit widths of the various tables. Thus, y1 can be 150 and y20 can be 200. Provision is made for twenty columns since studies indicate that this is the maximum number normally desired on one page.

The major function control codes in the input text data are the tabulate code and the carrier, carriage, return code. The composition computer receives text up to the first tabulate code and then automatically composes it into a format dictated by x1...
