For grouped reference objects, the value specified for the top-level object is applied to
every object comprising the group, that uses the same tag placeholder.
If you do not assign a value to a tag placeholder at design time, you can provide the value
at run time using either a parameter file, or the /T parameter with the Display command.
For information about using these methods, see page 16-36 and page 16-37.
Defining tag placeholders for use in reference objects
You can use tag placeholders instead of (or as part of) a tag name, expression, command,
or embedded variable associated with a global object or group of objects.
These are the steps involved in setting up tag placeholders for global objects:
1. Define one or more tag placeholders at the global base object.
2. Create one or more reference objects linked to the base object.
For information about creating reference objects, see “Creating global objects” on
page 17-49.
3. For each reference object, assign a value to the tag placeholder (or placeholders)
defined at the base object.
You can assign a unique value to the same tag placeholder, for each different reference
object. For an example, see page 16-39.
To define tag placeholders for the global base object
1. Right-click the global base object (or group), and then select Global Object
Parameter Definitions.
2. In the Global Object Parameter Definitions dialog box, specify a tag placeholder
name (#1, for example) and optional description, as shown in this illustration:
You can define multiple tag placeholders for a single global object or group.
For grouped objects, the placeholder defined for the top-level object applies to all
objects in the group.
