Q

language A very high level language by Per Bothner based

on lazy generalised sequences. Q has lexical scope, and

some support for logic programming[?] and constraint

programming. The language includes small subsets of CommonLisp and Scheme.

Q was a test-bed for programming language ideas. Where APL

uses arrays for looping, Q uses generalised sequences which

may be infinite and may be stored or calculated on demand. It

has macros, primitives to run programs, and an

interactive command language.

Q is implemented in C++, and comes with an interpreter,

compiler framework, libraries, and documentation. It runs

on Linux and SUN-4 and should work on any 32-bit Unix.

Latest version: 1, as of 1993-06-07. Development stopped in

1994.
