Electronic Typesetting Program Programmer's Manual.

摘要

A new method of processing the data to make print masters (images from which printing plates are made) for artillery firing tables has been developed. The new system uses electronic typesetting, derived from the National Bureau of Standards Typographic System, to prepare data for a photocomposition machine. This is a programmer's manual with information on how the program works, how to alter it to produce artillery firing tables, and the structure of the Typographic System from which it is derived.
