DESCRIPTION

Define a property with the given name by the given expression. See SelectMol for a description of the expression syntax. Properties can be used in other property definitions or selections. The Select commands are actually just special cases of the DefProp commands, they defines the property with the name "selected". The following properties are used internally by the program and should not be defined by this command:

    all
    visible

The value of the "visible" property is maintained by the program, it is set for all atoms, bonds, distances and primitives that have their attributes (Style*) set in a way to make them visible. This is very convenient for selecting only visible items.

The "displayed" property is used by the program to decide which items should be displayed. It is not recommended to modify it, it is normally better to use the Style*
