Modern data processing achieves miracles in reducing mountains of paperwork to compact "molehills" of cards or tapes. But what then? How do you move that com­ pressed data across town or across country? If you're practical (and time-and-cost-con­ scious), you telephone it. Bell System DATA-PHONE service can trans­ mit it over regular telephone lines at great speed-and at regular phone-call rates. DATA-PHONE service is a natural extension of your regular phone service, giving you integrated information handling that pays off in important time savings, better control of costs and greater all-round efficiency.

More than a calculator-Almost a computer ... and now with automatic input-$4350

THE WYLE SCIENTIFIC IS THE FIRST DESK-TOP COMPUTATIONAL CENTER designed specifically for the solution of complex scientific and engineering problems. Almost as simple to operate as an adding machine, it provides arithmetic capability, efficiency and speed never before available in a calculator. WITH AUTOMATED DATA ENTRY, it eliminates all the tedious, wasted time of multi-step repetitive arithmetic problem solving. You enter only the variables manually. All the repetitive procedures are run off automatically from a prepared program library of simple punchcards fed into the calculator reader. And you don't have to be a programmer or need additional equipment to prepare your own input library. You simply punch in your instruc­ tions by hand on a Wyle stored-program card, which has the calculator keyboard reproduced on it. With this auto­ mated input added to the Wyle Scientific versatility, you will solve complex problems at speed approaching that of a computer.

The Command-Control Information System for the Personnel and Administration Field Army is a part of this task. The fourth area of activity is the Personnel and Admin­ istration sub-system. The major effort here is to reduce manual record-keeping at the combat units to a minimum. Effort is being spent in personnel record-keeping, individ­ ual replacement, casualty reporting, rotation, and pay. Under the present method, a complete reulf(l is kept on file for each man, and the commander of a small unit sends in a comprehensive daily report concerning person­ nel in his unit. Under the new concept he will send only change information. He will receive from the computer CIRCULAR PROGRESSION center serving his unit, a comprehensive report concerning all personnel in his unit with specific mention being made of all situations requiring his action. The individual replacement function is perhaps one of the most important of all when considering increasing the tactical effectiveness of a unit. The problem exists of assigning the proper people to the proper jobs in both peacetime and wartime. With a computer it will be pos­ sible to carry out a more appropriate assignment. Operations The last major function to be automated is the Opera­ tions subsystem. This is the command post function through which the Division, Corps, or Army ·Commander controls his units. When automated, it should be able to carry out many staff functions better than the manual methods used at present. ,\t One activity is the maintenance of the Operations Situation Map. This is similar to the situation map in the Intelligence subsystem except that it has more concentra­ tion on friendly units. Here again, graphical display equipment will replace the grease pencil. The Commander or his staff will be able to interrogate the computer to determine specific information concerning pertinent events. If the information is not available at this complex, the other subsystems will be interrogated to obtain it. Besides the information retrieval aspects, a certain amollnt of computation would be done here. Such func­ tions as fallout prediction, radiological intensity charting, and status of key supply items will be performed. This will also be the center through which coordination with "Oh no sir, Mr. Supervisor,sir, I never drink on the job adjacent units and units of the other services or Allied sir, you see sir, "looped" is just an expression sir, natiollS will be done. when I said I was "looped," I meant, oh goodness h is quickly obvious that the full power of these sub­ gracious sir ..." systellls will be achieved when they are all operating to­ gether as a single system.
