Differences Between Properties and Variables


A variable always corresponds directly to a location in memory. A local variable is defined inside a procedure and is available only within that procedure. A member variable is defined inside a module, Class, or Struct and is sometimes called a field.


A property is a data element defined on a Library module or Class.
