	Each member of ''arglist'' is an argument passed to the procedure. Simple variables, such as strings and numbers, are passed by value. Complex variables, such as arrays and objects, are passed by reference. Each member of ''arglist'' can be used within the procedure to reference a value passed in. It follows standard variable naming procedure.		Each member of ''arglist'' is an argument passed to the procedure. Simple variables, such as strings and numbers, are passed by value. Complex variables, such as arrays and objects, are passed by reference. Each member of ''arglist'' can be used within the procedure to reference a value passed in. It follows standard variable naming procedure.

			To call a function, use the function name followed with parenthesis containing the arguments. If there are no arguments, it is still recommended that parenthesis be supplied, so it is clear that a function is being called.

	'''Note:''' If the return value is not stored in a variable or used in an expression, the procedure is called as a Sub procedure, and multiple arguments cannot be enclosed in parenthesis.
