This is a copy of my current .sti file: (blank line) STEP RA4 106 0 ! Start bit; byte 1 138 0 ! bit 0 170 0 202 0 234 0 266 0 298 0 330 1 ! ProgChange byte (0xC0) 362 1 ! bit 7 394 1 ! stop bit 426 0 ! Start bit; byte 2 458 0 ! bit 0 490 1 522 0 554 1 586 0 618 0 650 0 ! 0x0A 682 0 ! bit 7 714 1 ! Stop bit In case your wondering, its for "midi" data. Maybe your problem has something to do with formating, (i.e. exact number of spaces between columns, ect.) I have a single blank line at the top, also, although I doubt that's the problem. I've never tried anything except the exact format you see here. If your trying to watch the _option register (16c84) you may really get _rtcc depending on what bank you were in. Wish ya luck! p.s. Thankyou Andy for the "IP" command. I guess if all else fails just read the online instructions! -Hamilton At 08:10 AM 12/2/96 -0500, you wrote: > You got a stimulus file to work?
