Follow these steps to use tag placeholders and parameter lists:

1. In the Graphics editor, create graphic objects and assign tag placeholders to the

objects.

2. In the dialog box where the parameter list option appears, click on the Browse button

to open the Tag Browser.

3. Select the first tag or folder to add to the list and click OK. The tag or folder name

appears in the parameter list text box. At run time, this tag replaces placeholder #1.

4. To add another tag to the list, repeat steps 2 and 3. Each tag in the parameter list box is

separated from the previous tag by a comma. At run time, the second tag replaces
placeholder #2, the third tag replaces placeholder #3, and so on.

Example: Use a parameter list to replace tag placeholders
