Bliss

Abstract

A language, BLISS, is described. This language is designed so as to be especially suitable for use in writing production software systems for a speci c machine (the PDP-10): compilers, operating systems, etc. Prime design goals of the design are the ability t o p roduce highly e cient object code, to allow access to all relevant hardware features of the host machine, and to provide a rational means by which to cope with the evolutionary nature of systems programs. A major feature which contributes to the realization of these goals is a mechanism permitting the de nition of the representation of all data structures in terms of the access algorithm for elements of the structure.

Concepts and Notations for Concurrent Programming

“…In essence, coroutines are concurrent processes in which process switching has been completely specified, rather than left to the discretion of the implementation. Statements to implement coroutines have been included in discrete event simulation languages such as SIMULA I [Nygaard and Dahl, 1978] and its successors; the string-processing language SL5 [Hanson and Griswold, 1978]; and systems implementation languages including BLISS [Wulf et al, 1971] and most recently Modula-2 [Wirth, 1982].…”

Source program optimization with a generalized FOR statement

“…In BLISS [4] the value of an instance of an identifier name is a pointer to the memory word allocated to the identifier. This interpretation requires a "contents of' operator for which the symbol "."…”

“…b. A BLISS-like [4] interpretation of identifier names. c. No built-in data structures, except one-dimensional linear arrays.…”

Sémantique des structures de contrôle

“…Cette suppression du GO TO a conduit divers auteurs tels G. Bochman [4] ou C. T. Zahn [20], à définir de nouvelles structures de contrôle et même, pour certains, à proposer de nouveaux langages de programmation comme Bliss [19] ou Pascal [18].…”
