An '''immediate call''', or '''call''', is the operation in [[E]] which corresponds to the “method call”, “function call”, or sometimes “message send” of other object-oriented systems.

In E, an immediate call can only be performed on a [[near reference]], and it always returns "immediately" — within the same [[turn]], without waiting or blocking — as opposed to the [[eventual send]].

The E-language syntax for a call is
<var>recipient</var>.<var>verb</var>(<var>arg</var>, <var>arg</var>, ...)
where <var>recipient</var> and <var>arg</var> are [[expression]]s and <var>verb</var> is an [[identifier]] or [[string literal]].

Dynamic calls of arbitrary verb and argument count can be performed with [[E (object)#call/3|E.call]].

That's not just the best answer. It's the beetsst answer!
