DOS debugging quirk

Read Original

This technical article details a debugging anomaly in DOS where a simple assembly program outputs 'ok' when run normally but 'wrong' when traced in a debugger. The author explains that debuggers like DEBUG.EXE and Turbo Debugger manipulate memory below the program's stack pointer to handle interrupt traps, causing unexpected behavior if the program uses this region.
