GROUP command
The GROUP command is used to place a set of property controls in a Group box.
Group command syntax
The syntax of the command is as follows:
GROUP Name_of_Group
{ <properties to be enclosed in Group>
}
or
GROUP "Name of Group"
{ <properties to be enclosed in Group>
}
As shown above, the GROUP command requires that the properties in the group be specified within open and closed brackets, { }. If the name of the group contains embedded spaces, you must enclose the name in double quotes. You may also specify no name to the GROUP by specifying opening and closing double quote marks with no typing within them, for example:
GROUP ""
{ <properties to be enclosed in Group>
}
Note All Group names within a Diagram, Symbol, or Definition specification must be unique, even if they are located in different Chapters. So, for example, if you create a Group “x” in one Chapter of a definition, and create a second Group “x” containing different properties, all properties of both Groups will be contained within one Group “x” that will be located in the first Group's Chapter. If you want to have two or more Groups with similar names in the same specification, add a blank spaces to subsequent occurrences of the Group, for the above example, Group “x”.
