STSC
Scientific Time Sharing Corporation (STSC) was a pioneering timesharing and consulting service company which offered APL from its datacenter in Bethesda, MD to users in the United States and Europe. History Scientific Time Sharing Corporation (STSC) was formed in 1969 in Bethesda, Maryland by Dan Dyer, Burton C. Gray, and some of the people who originally implemented the programming language APL, notably Philip S. Abrams, Lawrence M. Breed, and Allen Rose. In 1970, STSC released ''APL*Plus'', a version of the ''APL\360'' language with many practical extensions oriented toward fostering business use of APL. Together with I. P. Sharp Associates, STSC made many enhancements to the APL language, including: * []FMT formatting * []VR and []FX, APL program Reflection (computer programming), reflection features * 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 th ...

APL (programming Language)
APL (named after the book ''A Programming Language'') is a programming language developed in the 1960s by Kenneth E. Iverson. Its central datatype is the multidimensional array. It uses a large range of special graphic symbols to represent most functions and operators, leading to very concise code. It has been an important influence on the development of concept modeling, spreadsheets, functional programming, and computer math packages. It has also inspired several other programming languages. History Mathematical notation A mathematical notation for manipulating arrays was developed by Kenneth E. Iverson, starting in 1957 at Harvard University. In 1960, he began work for IBM where he developed this notation with Adin Falkoff and published it in his book ''A Programming Language'' in 1962. The preface states its premise: This notation was used inside IBM for short research reports on computer systems, such as the Burroughs B5000 and its stack mechanism when stack machi ...
