The blit debugger: preliminary draft

ABSTRACT

This paper describes the evolution to date of a flexible debugger for C programs on the Blit, a multi-processing bitmap terminal. The debugger is of interest for the following reasons:-- it is assisted by the terminal software's elegant separation of the debugger process from its subject process.-- it resides autonomously in the terminal and is bound dynamically to arbitrary subject processes.-- it executes asynchronously with its subject.-- its implementation is distributed as a small process in the terminal and a large process in the host timesharing system.-- its user interface uses graphics and a mouse.An opinion about the most fruitful direction for further application of graphics is offered.
