PROGRAMMING
When companies order an IBM 1401 Data Processing System,methods-programming staffs are given the responsibility of translatingthe requirements of management into finished applications. 1401Programming Systems are helping cut the costs of getting the computerinto operation by simplifying and expediting the work of these methodsstaffs.
Modern, high-speed computers, such as the 1401, are marvelouselectronic instruments, but they represent only portions of dataprocessing systems. Well-tested programming languages for communicationwith computers must accompany the systems. It is through these languagesthat the computer itself is used to perform many of the tediousfunctions that the programmer would otherwise have to perform. A fewminutes of computer time in translating the program can be equal tomany, many hours of staff time in writing instructions coded in thelanguage of the computer.
The combination of a modern computer plus modern programming languagesis the key to profitable data processing. This brochure explains modernIBM Programming Languages and their significance to management.
Page 2:Here an operator points to machine language instructions for a newapplication being generated by the 1401 system on the 1403 high-speedprinter. Statements about the application which were written by theprogrammer are being translated internally to machine-coded language.
"What Is A 1401 Program?"
A program is a series of instructions that direct the 1401 as it solvesan application.
"What Is A Stored Program Machine?"
A stored program machine is one which stores its own instructions inmagnetic form and is capable of acting on those instructions to completethe application assigned. The 1401 uses a stored program.
"What Are 1401 Programming Systems?"
There are two types: (1) Systems that provide the programmer with asimplified vocabulary of statements to use in writing programs, and (2)Pre-written programs, which take care of many of the everyday operationsof the 1401.
What 1401 Programming Systems Mean To Management:
INCREASED PROGRAMMING EFFICIENCY
Programmers can concentrate on the application and results rather thanon a multitude of "bookkeeping" functions, such as keeping track ofstorage locations.
FASTER TRANSLATION OF MANAGEMENT REQUIREMENTS INTO USABLE RESULTS
Simplified programming routine
