Default Static vs constant

What is the difference between declaring something as Static vs declaring the same thing as a constant?
When does one use one over the other

 Eg

Static msg as String
msg= Save Changes

Versus

Const msg as String = "Save Changes"

Thanks

A static variable in a procedure holds the value even after the procedure ends. Variables have a scope, which means that it can be accessed through the whole module if it is a module level variable, or through the whole procedure in which it is defined.
When the procedure ends the variable loses its value if it is not a static variable.
Variables can hold different values but constants are used to represent a constant value.

It's got something to do with constants being constant and variables being variable - you can't vary a constant, but you can vary a variable
