A procedure is a series of VBA statements that resides in a VBA module, which you access in the Visual Basic Editor (VBE). A module can hold any number of procedures. A procedure holds a group of VBA statements that accomplishes a desired task. Most VBA code is contained in procedures.
You have a number of ways to call, or execute, procedures. A procedure is executed from beginning to end, but it can also be ended prematurely.
Some procedures are written to receive arguments. An argument is information that is used by the procedure and that is passed to the procedure when it is executed. Procedure arguments work much like the arguments that you use in Excel worksheet functions. Instructions within the procedure perform operations using these arguments, and the results of the procedure are usually based on those arguments.
