Collection-oriented languages

Article Abstract:

Collection-oriented languages supply high-level data abstractions and operations on them and provide implicit parallelism. Collection-oriented languages include FORTRAN 90, APL, SETL, CM-LISP, and Paralation LISP. Collection-oriented languages have aggregate data structures and the operations that manipulate them as a whole as primitives. These languages support sets, sequences, arrays, vectors, and lists. Collection-oriented operations include unary apply-to-each; nonunary apply-to-each; rearranging elements; and nested collections and operators. There are four classes of collection orderings: unordered, the foremost collection type in SETL; sequence-ordered, the basic data structure of LISP-like languages; grid-ordered, the basic data structure of APL-like languages; and key-ordered, the most general. The set of collection operations is either aggregate or apply-to-each.

All gloss and no substance

Article Abstract:

Many observers now believe that the editors of UK consumer magazines are putting style before substance. Their writing is often superficial and unoriginal, and they are too unwilling to offend their readers. Magazines have now developed a house style, and are determined to ensure that all contributors stick to this.
