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* commands for changing the visibility. It is very useful for molecules, however, but the molecule dialog (DialMol command) is more convenient for modifying it in this case.
The "movable" property is used by the program to decide which items are moved by rotations etc. It only has an influence for molecules, and the molecule dialog (DialMol command) command is more convenient for modifying it.
Some properties are predefined, they can be seen in the file:
$MOLMOLHOME/setup/PropDef
or with the HelpProp command.
