Jerry, I've been beta testing the Carmacon programmer software and when I use CVASM v5.8 to program various 16F877 *.OBJ files, the programmer will not read the files. This is with the Carmacon release and beta software. When I go back to CVASM v5.6, everything works fine. I have'nt talked to Carl at Carmacon yet. Note, v5.8 did fix the problem of calling routines in the 1000h and 1800h banks. I've posted this to both the Parallax and MIT lists. Thanks, - Tom ------------------------------------------------------------------------ Tom Handley New Age Communications Since '75 before "New Age" and no one around here is waiting for UFOs ;-)
