The Sub statement declares the name, arguments, and code that form the body of a Sub procedure.
This statement has the following form:
[Public [Default] | Private] Sub name [(arglist)] [statements] [Exit Sub] [statements] End Sub
|Public||(optional) A keyword that specifies that the constant is available to all procedures in all scripts|
|Default||(optional) A keyword that is used only with the Public keyword in a Class block to indicate that the
Sub procedure is the default method for the class.
An error occurs if more than one Default procedure is specified in a class.
|Private||(optional) A keyword that specifies that the constant is only available within the script where the declaration is made|
|name||(required) Specifies the name of the sub
Note: name must follow the standard variable naming conventions
|arglist||Specifies a list of variables representing arguments that are passed to the Sub procedure when it is called
This argument has the following syntax and parts:
ByVal - Indicates that the argument is passed by value
ByRef - Indicates that the argument is passed by reference
(if both ByVal and ByRef are omitted, the default is ByRef)
varname - Specifies the name of the variable representing the argument; follows standard variable naming conventions
Note: Commas separate multiple variables
|statements||Any group of statements to be executed within the body of the Sub procedure|
