Mathematical notation[ edit ] A mathematical notation for manipulating arrays was developed by Kenneth E. Iversonstarting in at Harvard University. Applied mathematics is largely concerned with the design and analysis of explicit procedures for calculating the exact or approximate values of various functions.
Such explicit procedures are called algorithms or programs. Because an effective notation for the description of programs exhibits considerable syntactic structure, it is called a programming language. This notation was used inside IBM for short research reports on computer systems, such as the Burroughs B and its stack mechanism when stack machines versus register machines were being evaluated by IBM for upcoming computers.
Iverson also used his notation in a draft of the chapter A Programming Language, written for a book he was writing with Fred BrooksAutomatic Data Processing, which would be published in InHerbert Hellerman, working at the IBM Systems Research Institute, implemented a part of the notation on an IBM computer, and it was used by students in a special high school course on calculating transcendental functions by series summation.
Students tested their code in Hellerman's lab. After this was published, the team turned their attention to an implementation of the notation on a computer system. One of the motivations for this focus of implementation was the interest of John L.
Lawrence asked Iverson and his group to help use the language as a tool to develop and use computers in education. Breed and Philip S. The basis of this implementation was described in detail by Abrams in a Stanford University Technical Report, "An Interpreter for Iverson Notation" inthe academic aspect of this was formally supervised by Niklaus Wirth.
This was used on paper printing terminal workstations using the Selectric typewriter and typing element mechanism, such as the IBM and IBM terminal.
Keycaps could be placed over the normal keys to show which APL characters would be entered and typed when that key was struck. For the first time, a programmer could type in and see proper APL characters as used in Iverson's notation and not be forced to use awkward English keyword representations of them.
Falkoff and Iverson had the special APL Selectric typing elements, anddesigned in latealthough no APL computer system was available to use them.
An example is the grade up character, which had to be made from a delta shift-H and a Sheffer stroke shift-M. This was necessary because the APL character set was much larger than the 88 characters allowed on the typing element, even when letters were restricted to upper-case capitals.
APL gained its foothold on mainframe timesharing systems from the late s through the early s, in part because it would support multiple users on lower-specification systems that had no dynamic address translation hardware.
Somewhat later, as suitably performing hardware was finally growing available in the mid- to lates, many users migrated their applications to the personal computer environment.
The ability to programmatically communicate with the operating system for information and setting interpreter system variables was done through special privileged "I-beam" functions, using both monadic and dyadic operations.
SV, which was a continuation of the same product, but which offered shared variables as a means to access facilities outside of the APL system, such as operating system files.
