Before Unicode, APL interpreters were supplied with fonts in which APL characters were mapped to less commonly used positions in the ASCII character sets, usually in the upper 128 code points. These mappings (and their national variations) were sometimes unique to each APL vendor's interpreter, which made the display of APL programs on the Web ...
a file system to store APL variables outside of the APL environment; STSC continued to make enhancements to the interpreter, notably improving the performance of many of the primitive functions. In 1985, Dan Dyer of STSC and Ian Sharp of I. P. Sharp Associates jointly received the Kenneth E. Iverson Award for Outstanding Contribution to APL.
First introduced for use at IBM in 1966, the APL\360 [21] [22] [23] system was a multi-user interpreter. 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. [24]
Two such programs were included: a slightly modified version of APLSV, IBM's APL interpreter for its System/370 mainframes, and the BASIC interpreter used on IBM's System/3 minicomputer. Consequently, the 5100's microcode was written to emulate most of the functionality of both a System/370 and a System/3.
In computer programming, a programming language implementation is a system for executing computer programs. There are two general approaches to programming language implementation: [1] Interpretation: The program is read as input by an interpreter, which performs the actions written in the program. [2]
As of 2010, Unicode allows APL to be stored in text files, published in print and on the web, and shared through email and instant messaging. Entering APL characters still requires the use of either a specific input method editor or keyboard mapping, or of a specific touch interface. APL keyboard mappings are available for free for the most ...
I. P. Sharp Associates (IPSA) was a major Canadian computer time-sharing, consulting and services firm of the 1970s and 1980s.IPSA is well known for its work on the programming language APL, an early packet switching computer network named IPSANET, and a powerful mainframe computer-based email system named 666 Box, stylized as 666 BOX.
Kenneth Eugene Iverson (17 December 1920 – 19 October 2004) was a Canadian computer scientist noted for the development of the programming language APL.He was honored with the Turing Award in 1979 "for his pioneering effort in programming languages and mathematical notation resulting in what the computing field now knows as APL; for his contributions to the implementation of interactive ...
