isInside
|
The isInside function determines whether or not the specified
{key} is a member of the {target} Dictionary. If the {key} is found, true is returned.
If {key} is not found, false is returned. The isInside
function uses the isIdentical predicate.
The isInside function is used to determine if a symbolic key is in a specified Dictionary. It returns a Boolean value true if found in the structure or false if not found. If the desired information is the index of the symbolic key, then the inside function should be used instead
(isInside key obj) Returns true if the key was found. Returns false if the key was not found.
