document: The BLISS programming language : a history The BLISS programming language was invented by William A. Wulf and others at Carnegie-Mellon University in 1969 , originally for the DEC PDP-10 . BLISS-10 caught the interest of Ronald F. Brender of DEC -LRB- Digital Equipment Corporation -RRB- . After several years of collaboration , including the creation of BLISS-11 for the PDP-11 , BLISS was adopted as DEC 's implementation language for use on its new line of VAX computers in 1975 . DEC developed a completely new generation of BLISSs for the VAX , PDP-10 and PDP-11 , which became widely used at DEC during the 1970s and 1980s . With the creation of the Alpha architecture in the early 1990s , BLISS was extended again , in both 32 - and 64-bit flavors . BLISS support for the Intel IA-32 architecture was introduced in 1995 and IA-64 support is now in progress . BLISS has a number of unusual characteristics : it is typeless , requires use of an explicit contents of operator -LRB- written as a period or ` dot ' -RRB- , takes an algorithmic approach to data structure definition , has no goto , is an expression language , and has an unusually rich compile-time language . This paper reviews the evolution and use of BLISS over its three decade lifetime . Emphasis is on how the language evolved to facilitate portable programming while retaining its initial highly machine-specific character . Finally , the success of its characteristics are assessed
