OFLAG

The oflag command can be used to set an object's flags. For example:

oflag sword magic +wield bless -brittle

That command will toggle the sword's magic flag, make it wieldable and blessed, and remove its brittle flag (if it was set). (Abbreviations are permitted.) The add(+) and remove(-) operators continue to hold once invoked until reversed. The command assumes a toggle operation until it encounters either a + or a -.

If you enter oflag without any flags, the flags for the specified object will be displayed.
