I'm using the Hi Tech PIC18 compiler within MPLAB. When debugging, I want all the local variables to be listed in the Locals window, but only a small subset are usually listed. Perhaps due to optimization, but I've disable all optimization in the Build Options. Does anyone have a trick to force variables to be listed?
