A function call binds parameter names to argument values or,
equivalently, argument values to parameter names, so it doesn't really
matter whether you call it "parameter (name) binding" or "argument
(value) binding". It's the same operation, just emphasising either the
source of the names or the source of the values.
I normally talk about binding names to values, since a name can only
refer to one value at a time, but there may be multiple names bound to
any given value. Hence, I prefer to call this process "parameter
binding" - it's the step of assigning a value to each of the parameter
names before the body of the function starts executing.
