Procedure Arguments

In most cases, a procedure needs some information about the circumstances in which it has just been called. A procedure that performs repeated or shared tasks uses different information for each call. This information consists of variables, constants, and expressions that are passed to the procedure when it is called. Each value passed to a procedure is called an argument.
