Variables are used to store information temporarily. As a program runs, it holds values temporarily in memory.
Variables are names that the program associates with specific locations in memory.
The value to which the program refers in these areas can change throughout a session of program operation. Each variable has a specific type , that indicates how much memory the data requires and the operations that can be performed on that kind of data. End Sub Variables declared within a procedure are not available to other procedures and they only retain values for the life of that procedure. This refers to a variable's scope . However, these variables are not available to procedures outside of the module in which they are declared.
