I have made a minor update to the PIC development environment at http://www.embedinc.com/pic/dload.htm. I now believe that recent problems reported here were due to the MPLABDIR environment variable not being set. Better error messages are now emitted by ASMPIC, and a note about MPLABDIR added to the web page where the environment is downloaded. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
