With no argument, an
Dictionary
of
String
valued objects is returned.
The name of each dictionary element corresponds to a variable name in
the current OS environment and its value corresponds to the value of
that variable when the interpreter was invoked.
Alternatively, a single
String
argument can be supplied, in which case the value of the OS
environment variable in effect when the interpreter was invoked is
returned.
If no variable with the supplied name exists, then
NULL
is returned.
