A procedure is a set of instructions that works as a unit and can be called from a test or another procedure. A procedure contains a name and description, parameters and variables, programming code, and a return value.
This chapter only describes user-defined procedures, which can either be a function that returns one type of value or a subroutine that returns no values. You can declare user-defined procedures either in the Program, System or Driver modules, or in Forms. Once a procedure is declared, you call a procedure by specifying the procedure name and its parameters.
