Swap

Exchanges the values of two variables

Syntax
   Declare Sub Swap  ( ByRef a As Any, ByRef b As Any )

Usage
   Swap a, b

Parameters
   a
      A variable to swap.
   b
      A variable to swap.

Description
   Swaps the value of two variables, including UDT instances (swaps all 
   data members).

   Note: When the data are referenced by a pointer, alone or within a 
   descriptive structure (a UDT, for example), Swap only exchanges the 
   values of the pointers or the contents of the descriptive structures 
   without accessing data themselves.
   For var-len strings, Swap only exchanges the descriptors of the strings 
   rather than reallocate memory for exchange all strings data characters.
   For UDTs, Swap simply exchanges the contents of the structures, without 
   any operators or methods being called.

Example
   ' using swap to order 2 numbers:
   Dim a As Integer, b As Integer

   Input "input a number: "; a
   Input "input another number: "; b
   If a > b Then Swap a, b
   Print "the numbers, in ascending order are:"
   Print a, b
