History
APL stands for "A Programming Language." It was created in the 1960's by Ken Iverson and his colleagues at IBM. Mathematically inspired, its main purpose was to serve as a powerful executable notation for mathematical algorithms. What APL is best known for is its use of non-ASCII symbols, including some Greek letters. It is a dynamically typed interactive, array oriented language with a dynamic scope. In APL, all expressions are evaluated from right to left.
Significant Language Features
- Non-Standard Character Set - APL makes use of a character set which
contains some non-ASCII characters, including some Greek letters.
- Dynamic Array Universe - APL's environment consists of arrays,
created dynamically.
- Interaction - APL is an interactive language.
Areas of Application
- Mathematical Algorithms
- Statistics
