Hi all, I'm new here. I read the Franc's message and I wanna ask your something. I'm working with Keil's c51 v5.10 for the half of year (I use also Ceibo debugger) and suddenly the debugger got crazy ( I can't set breakpoints on lines with simple operation like a=5, but hey, he gave me the options to put a breakpoint on comments!!!). I send details to Ceibo and the answer was "Do not use the optimize command in the compiler because it affects the
debug information." . I never messed with optimization and now I can't find the information about it.Especially about how I disable the optimization. Thank you.
