Sometimes the terms function argument and
function parameter are used interchangeably. In Shang language, they are
different.
Apart from input and output arguments, a function may have a number of
parameters.
These are attributes of the
function that can be used to modify the behavior of the function after
the function is created. A parameterized function can be viewed as either a
family of functions, from which one can pick given the parameter value, or
a function with a state that can be modified.
