I use as OS both Win98 and Win2000. But while compiling my programs, starting from files in assembler, all all runs Ok, when I use Win 98 when I work with Win 2000 ,also with MPLAB 7,5, I get in the Output window the classic reply "BUILD SUCCEEDED", but in my directory there are all files but the hex file. Where is it gone? Thanks Renzo -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
