When companies order an IBM 1401 Data Processing System,
methods programming staffs are given the responsibility of translating
the requirements of management into finished applications. 1401
Programming Systems are helping cut the costs of getting the computer
into operation by simplifying and expediting the work of these methods
staffs. Modern, high speed computers, such as the 1401, are marvelous
electronic instruments, but they represent only portions of data
processing systems. Well tested programming languages for communication
with computers must accompany the systems. It is through these languages
that the computer itself is used to perform many of the tedious
functions that the programmer would otherwise have to perform. A few
minutes of computer time in translating the program can be equal to
many, many hours of staff time in writing instructions coded in the
language of the computer. The combination of a modern computer plus modern programming languages
is the key to profitable data processing. This brochure explains modern
IBM Programming Languages and their significance to management. Page 2: Here an operator points to machine language instructions for a new
application being generated by the 1401 system on the 1403 high speed
printer. Statements about the application which were written by the
programmer 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 solves
an application.
"=What Is A Stored Program Machine?=" A stored program machine is one which stores its own instructions in
magnetic form and is capable of acting on those instructions to complete
the application assigned. The 1401 uses a stored program.
"=What Are 1401 Programming Systems?=" There are two types: (1) Systems that provide the programmer with a
simplified vocabulary of statements to use in writing programs, and (2)
Pre written programs, which take care of many of the everyday operations
of the 1401.
=What 1401 Programming Systems Mean To Management:= INCREASED PROGRAMMING EFFICIENCY Programmers can concentrate on the application and results rather than
on a multitude of "bookkeeping" functions, such as keeping track of
storage locations. FASTER TRANSLATION OF MANAGEMENT REQUIREMENTS INTO USABLE RESULTS Simplified programming routines allow programmers to write more
instructions in less time. SHORTER TRAINING PERIODS Programmers use a language more familiar to them rather than having to
learn detailed machine codes. REDUCED PROGRAMMING COSTS Many pre written programs are supplied by IBM, eliminating necessity of
customers' staffs writing their own. MORE AVAILABLE 1401 TIME Pre written programs have already been tested by IBM, reducing tedious
checking operations on the computer. EASIER TO UNDERSTAND PROGRAMS Programs are written in symbolic or application oriented form instead of
computer language. This enables management to communicate more easily
with the programming staff. FASTER REPORTS ON OPERATIONS Routines such as those designed for report writing permit faster
translation of management requirements into usable information.
IBM Programming Systems: Symbolic Programming Systems These systems permit programs to be written using meaningful names
(symbols) rather than actual machine language. Autocoder This is an advanced symbolic programming system. It allows generation of
multiple machine instructions from one source statement, free form
coding, and an automatic assembly process through magnetic tape. COBOL COBOL is a problem oriented programming language for commercial
applications... Continue reading book >>
