The Laning and Zierler system was the first programming language to parse algebraic formulae. When Hopper became aware of that language in 1954, it altered the trajectory of her work. [4] FLOW-MATIC was the first programming language to express operations using English-like statements. [3]
COBOL (/ ˈ k oʊ b ɒ l,-b ɔː l /; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language.
GnuCOBOL translates a COBOL program (source code) into a C program. The C program can then be compiled into the actual code used by the computer (object code) or into a library where other programs can call (link to) it. On UNIX and similar operating systems (such as Linux), the GNU C compiler is used for this process.
At the height of COBOL usage in the 1960s through 1980s, the IBM COBOL product was the most important of any industry COBOL compilers. In his popular textbook A Simplified Guide to Structured COBOL Programming , Daniel D. McCracken tries to make the treatment general for any machine and compiler, but when he gives details for a particular one ...
The application program interfaces of IBM's mainframe operating systems is defined as a set of assembly language "macro" instructions, that typically invoke Supervisor Call (SVC) [e.g., on z/OS] or Diagnose (DIAG) [on, e.g., z/VM] instructions to invoke operating system routines. It is possible to use operating system services from programs ...
The powerful Burroughs COBOL compiler was also a one-pass compiler and equally fast. A 4000-card COBOL program compiled as fast as the 1000-card/minute readers could read the code. The program was ready to use as soon as the cards went through the reader. Figure 4.5 From the ACM Monograph in the References. Elliot Organick 1973.
The machine matched COBOL so closely that the COBOL compiler was simple and fast, and COBOL programmers found it easy to do assembly programming as well. In the original instruction set, all operations were memory-to-memory only, with no visible data registers.
FACT is an early discontinued computer programming language, created by the Datamatic Division of Minneapolis Honeywell for its model 800 series business computers in 1959. FACT was an acronym for "Fully Automatic Compiling Technique". [1] It was an influence on the design of the COBOL programming language.
