I know this has been covered before, but I haven't been developing PIC code since version 3.22 and now that I've "upgraded" to 3.40 I can't build a project. I won't even mention the half hour spent trying to add an .asm file to the project (I finally had to download a .pdf file from Microchip's site to figure it out), or the fact that there was no MLASM.EXE file in the distribution directory (I copied MPASMWIN.EXE to MPASM.EXE and it seems to be assembling). My current problem is that after the assemler has run I get a message saying that "MPLAB cannot find the .hex file" and the damn file is right in the project directory! If anybody can help me out on this one, I'd appreciate it. And if anyone from Microchip is on this list, all I can say is that you took a piece of software that worked and made it a LOT harder to use. No one wants to spend a few hours figuring out the quirks in your software. I'm afraid to see what your new version 4 software will be like. Keith Keith D.
