Call
A call is the invocation of a function or method.
Related concepts: FunctionMethodReturn
Closest Wikipedia entry: Subroutine — In computer programming, a function or subroutine is a sequence of program instructions that performs a specific task, packaged as a unit. This unit can then be used in programs wherever that particular task should be performed. Functions may be defined within programs, or separately in libraries that can be used by many programs.
