Hi, I was thinking of adding a breakpoint opcode to python to enable less invasive debugging. I came across posts from 1999 by Vladimir Marangozov and Christian Tismer discussing this issue but the links to the code are all out of date. Did anything come of this? Is this a good approach to take? - if so why was this never incorporated? Cheers, Andrew Dr. Andrew Perella Chief Software Architect Eutechnyx Limited.
