Arguements

Values passed to procedures.

Procedure Declaration

[AccessSpecifier] Sub ProcedureName ([ParameterList]) [Statements] End Sub

Procedure Call

a type of statement that causes the procedure to execute

static local variables

allows a value to be retained from one call of the function to another

Modularize

break an applications code into small manageable procedures. ex breaking a book into chapters

step over command

causes the currently highlighted line to execute

step into command

causes the currently highlighted line to execute when in break mode. Allows you to single step through a procedure or function when it is called

step out command

completes remainder of procedure or function execution without single stepping

ByVal

keyword indicates that arguments passed into the variable are passed by value

Byref

keyword that causes arguments to be passed by reference to the parameter

sub

name of procedure

By Value

only a copy of the argument is passed to the procedure, so it cant make changes to the original arguement

Pascal casing
