An Extended Basic Compiler With Graphics Interface For The Pdp 11 50 Computer

The design and implementation of an extension to the Basic programming language for use on the PDP-11/50 computer system has been described. The implementation consists of a compiler which generates code to be assembled and loaded into the computer system. An interface with C programs in the system library, which allows extended Basic to perform as an extensive graphics language, has been discussed. The design goals, solutions, and recommendations for further expansion of the system have been presented. The compiler was implemented in the C-programming language with the UNIX operating system as supported by the PDP-11/50 at the Naval Postgraduate School Computer Laboratory. (Author).
