Demonstration: A stepper for Armed Bear Common Lisp (ABCL)

In this paper a stepper tool for the Armed Bear Common Lisp (ABCL) implementation is proposed, describing its features and implementation related details. ABCL does not currently have a stepper and the addition of one can help improve the quality of the code designed to run in the implementation, and also it can be useful to assist in the debugging process of Common Lisp (CL) portable code. &nbsp
