The remProp function deletes the property {propName} from the property list associated with the symbol {sym}. If the {propName} does not exist, a value of false is returned; otherwise a value of true is returned.


The remProp function is a function defined as part of the standard Lisp language. There are five functions that deal with assigning, acquiring and removing a property from a property list of a symbol: putProp, getProp, proplist, proprecord, and remProp. The notion of a property for a symbol consists one or more property bindings: a property-descriptor followed by a property-name. While Lisp supports the traditional Lisp functions for properties, the Structure and Dictionary objects offer a more flexible way of storing attribute bindings.
