BLISS

# BLISS Summary BLISS is a system programming language developed at Carnegie Mellon University in 1970 by W. A. Wulf, D. B. Russell, and A. N. Habermann, featuring block structure, expression-based syntax, and support for exception handling and macros without goto statements. Though it was the leading system language before C emerged, BLISS fell into obscurity as C gained popularity, though DEC maintained and used it extensively for operating systems like OpenVMS through the 1980s. The language was designed specifically for system software implementation with access to machine-specific features while omitting built-in I/O facilities.
