The diagram above is a minimum PLD function similar to classic, empty functions. The only challenge here is lack of executable details.
This 2nd diagram show one way of presentaing executable details. This is key to our success, so we need to work a bit on this.
This last diagram show a possible single-step debugging technique. Notice that we display variable values and highlight diagram parts that is the next step. Again – we need to experiment a bit with this to see what works and what doesn’t.
