PIS Glossary 에 argument 와 parameter 를 구분하여 정의하고 있기도 하고,
의미도 다르므로 구분이 필요하리라 생각되어요.
argument
When a function is invoked, an argument is passed for each parameter
of that function. The parameter is the variable that refers to the
argument. The argument is the object passed at invocation time. In addition,
applications can take (command line) arguments that show up
in the Array[String] passed to main methods of singleton objects.
parameter
Functions may take zero to many parameters. Each parameter
has a name and a type. The distinction between parameters and arguments
is that arguments refer to the actual objects passed when a
function is invoked. Parameters are the variables that refer to those
passed arguments.
그래서, 저는 주로 parameter 는 매개변수로, argument 는 인자(또는 인수) 를 사용합니다.
