Hi Everyone, Just downloaded an old MPSIM documentation accidentally from Microchip web site: http://ww1.microchip.com/downloads/en/DeviceDoc/30027i.pdf This is written in 1995 I believe, and is an individual simulator (aka not intergrated into MPLAB). The documentation talks about commands that you can use for debugging / similar to gdb or SoftIce or WinDbg or many other debuggers. I found it quite useful especially with the command files and journal files, but I can't seem to find a "command prompt" in the new, integrated MPSIM, only the clicks and Fxx buttons. Is there any way to use these commands?
