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 {Common Lisp} 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-bITUnix. Latest version: 1, as of 1993-06-07. Development stopped in 1994. Start . E-mail: Per Bothner . (2000-05-22)
