What Does A Programming Language (APL) Mean?A Programming Language (APL) was first described in a 1962 book of the same name by Kenneth E. Iverson. APL is an interactive and interpreted third-generation language (3GL) oriented toward the rigorous expression of mathematical notations by a computer in an interpretive way. APL has a concise representation of arrays and operators, which are manipulated them while allowing for the implementation of abstract problem solving. It does this from diverse domains and expresses algorithms independent of computing platform specifics.
Today, APL is provided in integrated development environments (IDE) by a number of commercial and non-commercial vendors.
Before coming to be known as APL, the language was simply known as Iverson's Language.
