Abstract

It is often desirable that all word registers, i.e., memories, in a data processing machine be the same in length and similar in structure. It is economic to process numeric data in a compact form, with commas and similar format insertions deleted. When the data is printed out, format can be inserted from a format containing register the same size as the data register. This is effected by alternately acting upon a character position of the data register and a character position of the format register. The drawing illustrates the data and format registers.

Format Control Scheme

It is often desirable that all word registers, i.e., memories, in a data processing machine be the same in length and similar in structure. It is economic to process numeric data in a compact form, with commas and similar format insertions deleted. When the data is printed out, format can be inserted from a format containing register the same size as the data register. This is effected by alternately acting upon a character position of the data register and a character position of the format register. The drawing illustrates the data and format registers.

Many of the character positions of the format register may contain a code which inhibits printer response to format reading. Each special format designation is in a code to which the printer responds without further code translation. Character positions of the data register and the format register are acted upon alternately and in sequence.

The format is preselected as desired. A common format is the decimal point and comma format conventionally used in the writing of money amounts. In this case, each third format character is generally a comma, with exceptions such as the properly located decimal as shown.

Since printing is to be high-order first, the data and format registers are read high order first. A field mark, shown as F in the drawing, controls spacing of the printer. The format register is first individually scanned until the field mark F is located. Data and format are then read concurrently or alternately with the printer acting first in response to data.

Usually, conventional...
