Under Database in the program tree, there are several items that can be used to add or modify descriptions, symbols, and comments.
- We double-click on Address/Symbol, and the “Address and Symbol Editor” opens. We can double-click on any existing symbol or address description, and an editing window opens. At the bottom of the window, we see that address descriptions and symbols can be added for an address not currently on the list.
- We can edit Page Titles and Rung Comments in the same way. We open the Rung Comments item by double-clicking on it. Rung comments and page titles are often associated with the output instruction for a rung. This way, if rungs are added or deleted, the comment follows the output, not the rung number in the program.
As with the Address/Symbol editor, new comments or page titles can be added using the “Add New Record” button in the Rung Comment editor. When adding comments this way, the editor allows the choice of adding the comment to the rung number or the output instruction.
