The Layout command provides layout control throughout a definition, in a tab (or chapter) and in a group.
Layout in a definition
The last layout command specified in a definition is the one that takes precedence. The layout specified pertains to all tabs (or Chapters) in the definition, including individual properties, and entire groups of properties (not the properties in the group if overridden by a layout statement in the group).
Layout in a tab (or chapter)
The last layout command specified in a chapter is the one that takes precedence. The layout specified pertains to all individual properties in the chapter, and entire groups of properties.
Layout in a group
Layout may be specified with a Group statement. Groups, in general, cannot be specified in other groups.
