Dear All, I have tried to run Dhry.uv2 in \keil\c51\example\dhry and it works. However, I tried to sdd some empty line between statements in every module such as Dhry.c or time.c ,I found when I type "step into" key , the cursor didn't match with new module ,it match with the posititon in old module.I found it seem to be due to DMO file Because after build only .DMO keep old time. other is update to new time. It is my big trouble ,because I couldn't study next when this bottleneck is still existed . BR.
Ahhhhh. I just remembered. The .DMO file is a pre-built and linked program file for those examples that are larger than 4K. I seem to recall that there is a debugger script that loads the DMO file instead of the linker output (which isn't created anyway since the file would be larger than 2K). I guess the answer is that this example is too large to build using the FREE evaluation tools. Jon
