That said, we have to be aware of these "compound" instructions because Skip instructions only skip one -- using a skip instruction right before a compound instruction can lead to troubles. 2. The SX/B documentation is online in the help file. 3. Sure -- just make sure that you don't create an electrical conflict (both outputs and in opposite states); you can prevent programming errors from doing damage by making the connection through a 1K resistor (this limits the current enough to prevent damage to either chip). ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=97847#m97852 Need assistance?
