Excerpt: APL (named after the book A Programming Language) is an interactive array-oriented language and integrated development environment which is available from a number of commercial and non-commercial vendors and for most computer platforms. It is based on a mathematical notation developed by Kenneth E. Iverson and associates which features special attributes for the design and specifications of digital computing systems, both hardware and software. APL has a combination of unique and relatively uncommon features that appeal to programmers and make it a productive programming language: APL is used in scientific, actuarial, statistical, and financial applications where it is used by practitioners for their own work and by programmers to develop commercial applications.
It was an important influence on the development of spreadsheets, functional programming, and computer math packages. It has also inspired several other programming languages. It is also associated with rapid and lightweight development projects in volatile business environments. The first incarnation of what was later to be the APL programming language was published and formalized in A Programming Language, a book describing a notation invented in 1957 by Kenneth E. Iverson while at Harvard University. Iverson had developed a mathematical notation for manipulating arrays...
