The length function returns the number of elements in a Vector.
The length function returns the number of characters in a String or Text
argument.
The length function takes a Symbol argument and returns the number of
characters in the global value of a Symbol .
The length function returns the number of bindings in the Structure.
The length function returns the number of bindings in the Dictionary.
The length function returns the number of bindings in the Directory.
The length function returns the number of rows in a Brick.
The length function returns the number of elements in a Matrix.
The length function returns the number of elements in a NumMatrix.
The length function returns the number of elements in a Pair.
The length function returns the number of elements in a List.
The length function returns the number of objects currently stored in the
specified Object Repository database archive file {aGor}.
Usage The length function should be used when you need to determine the
number of elements in a Structure, Dictionary, Directory, Matrix, Vector, Pair or List. This type of counting is called a shallow
count in which embedded collection objects are counted as one. An alternate function,
the count function, performs a deep count, which is used to determine
the total number of items in an object, including the items in embedded collection
objects. The length function should be used when you need to determine the number of
characters in a Text or String. The length function should be used when you need to determine the number of
characters in a Symbol's global value. The length function should be used when you need to determine the number of
fields in a Brick. The length function is used to query the Object Repository for the number of
objects in the Object Repository. If the physical size of the Object Repository is the
information needed, see the sizeof function. String
