| 1 | IBM 1401 Programming Systems |
| 2 | 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 . |
| 3 | 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 . |
| 4 | The combination of a modern computer plus modern programming languages is the key to profitable data processing . |
| 5 | This brochure explains modern IBM Programming Languages and their significance to management . |
| 6 | 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 . |
| 7 | What Is A 1401 Program ? |
| 8 | A program is a series of instructions that direct the 1401 as it solves an application . |
| 9 | What Is A Stored Program Machine ? |
| 10 | 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 . |
| 11 | The 1401 uses a stored program . |
| 12 | What Are 1401 Programming Systems ? |
| 13 | 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 . |
| 14 | What 1401 Programming Systems Mean To Management : |
| 15 | INCREASED PROGRAMMING EFFICIENCY |
| 16 | Programmers can concentrate on the application and results rather than on a multitude of “ bookkeeping ” functions , such_as keeping track of storage locations . |
| 17 | FASTER TRANSLATION OF MANAGEMENT REQUIREMENTS INTO USABLE RESULTS |
| 18 | Simplified programming routines allow programmers to write more instructions in less time . |
| 19 | SHORTER TRAINING PERIODS |
| 20 | Programmers use a language more familiar to them rather than having to learn detailed machine codes . |
| 21 | REDUCED PROGRAMMING COSTS |
| 22 | Many pre_-_written programs are supplied by IBM , eliminating necessity of customers ' staffs writing their own . |
| 23 | MORE AVAILABLE 1401 TIME |
| 24 | Pre_-_written programs have already been tested by IBM , reducing tedious checking operations on the computer . |
| 25 | EASIER TO UNDERSTAND PROGRAMS |
| 26 | Programs are written in symbolic or application - oriented form instead_of computer language . This enables management to communicate more easily with the programming staff . |
| 27 | FASTER REPORTS ON OPERATIONS |
| 28 | Routines such_as those designed for report writing permit faster translation of management requirements into usable information . |
| 29 | IBM Programming Systems : |
| 30 | Symbolic Programming Systems These systems permit programs to be written using meaningful names ( symbols ) rather than actual machine language . |
| 31 | 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 . |
| 32 | COBOL |
| 33 | COBOL is a problem - oriented programming language for commercial applications . COBOL permits a programmer to use language based on English words and phrases in describing an application . |
| 34 | Input<sol>Output Control System This system provides the programmer with a packaged means of accomplishing input and output requirements . |
| 35 | Utility Programs These are pre_-_written instructions to perform many of the everyday operations of an installation . |
| 36 | Subroutines These are routines for multiplication , division , dozens conversion , and program error detection aids . |
| 37 | Tape Utilities These are generalized instructions , particularly useful to 1401 customers who also use larger data processing systems . They facilitate the transfer of data between IBM cards , magnetic tapes , and printers . They also provide for some 1401 processing while the transfer of data is taking place . |
| 38 | Tape Sort Programs |
| 39 | Data can be sorted and classified at high speed for further processing by use of these generalized sorting routines . |
| 40 | Report Program Generator |
| 41 | The programmer uses simplified , descriptive language with which he is already familiar to obtain reports swiftly and efficiently . |
| 42 | FORTRAN ( Contraction of FORmula TRANslator ) |
| 43 | Engineers and mathematicians state problems in familiar algebraic language for solution by the computer . |
| 44 | RAMAC File Organization |
| 45 | Routines are supplied for simplifying organization of records for storage in the 1401 Random Access File . |
| 46 | Here 's how one of the 1401 programming systems — Report Program Generator — works to increase programming efficiency |
| 47 | 1401 computers produce important reports for management in record time because_of their outstanding processing and printing abilities . |
| 48 | In addition to this rapid machine processing of input data used in reports , still more speed is achieved by the rapid preparation of programs to produce the reports . This is possible because_of the IBM Report Program Generator , a unique system which permits programs to be created with a minimum of time and effort . This example illustrates how the Report Program Generator simplifies the preparation of one part of an Expense Distribution Report ( The Major Total Line ) : Without the Report Program Generator , the program to get the Major Total Line would be written out in detail , step by step : But with the Report Program Generator , all the programmer has to write are these two statements : It 's just as easy to write the statements to generate the rest of the report ! |
| 49 | The 1401 itself does the work of converting the programmers ' statements into the detailed instructions . |
| 50 | The Report Program Generator is an example of what IBM Programming Systems can accomplish . |
| 51 | With IBM you can be certain of total systems support for maximum profitability . |
