ISEMPTY

Purpose:

Returns 1 if the input series is empty.

ISEMPTY(series)

series

Optional. A series to test, defaults to the current Window.

An integer, 1 if the input series is empty (i.e. length == 0), else 0.

a = {1};

b = {};

c = a * b;

isempty(a) == 0

isempty(b) == 1

isempty(c) == 1

An empty series has a length of 0.

The syntax a = {} creates an empty series.

ISEMPTY returns 1 if the input is not a series.

See ISWINEMPTY to determine if a Window contains a series.
