Programming Languages and Compilers

Real-time programming is required for systems like airline reservations where data must be processed immediately to ensure accuracy and prevent double-booking.

COBOL (Common Business-Oriented Language) was designed specifically for business, finance, and administrative systems for companies and governments.

Assembly language is tied to the specific instruction set of a processor architecture. This makes code non-portable, which is considered a significant demerit compared to high-level languages.

AHPL stands for A Hardware Programming Language, which is a hardware description language used for designing digital systems.

PC/M (often referred to as CP/M) was a popular operating system and system programming environment for early Intel-based microcomputers.

COMAT is a historical high-level language that was designed to incorporate the simple, readable style of BASIC.

Compilers and interpreters are software programs that translate high-level source code into machine-executable code.

ALGOL, SNOBOL, and FORTRAN were all languages used on early IBM mainframes. Miranda is a functional programming language developed much later (1985) and was not used on the IBM 7000 series.

C++ is a well-known object-oriented programming language, being an extension of C with classes. C is a procedural language, and ADA and FORTRAN are also primarily procedural.

AHPL stands for A Hardware Programming Language, which is a hardware description language used for describing digital systems.

BCPL (Basic Combined Programming Language) was designed to facilitate structured programming and served as the precursor to B and C.

Lex is a classic Unix utility designed specifically to generate lexical analyzers (scanners) from regular expression specifications. Yaac is a parser generator, while TeX and EQN are formatting tools.
