Use to suspend program execution when a condition you
specify becomes true. The condition may be
  - A variable name
  - A relational statement
 
A relational statement is constructed using the operators
=, <>, >, <, >=, or <=.
 
If you use the simpler form and just enter a variable name
or an expression, QuickBASIC assumes the relation <> 0. For
example, entering X + Y yields the expression X + Y <> 0.
 
Add Watch
    - Displays the values of variables as they change
      during program execution
    - Does not suspend program execution
A Watchpoint
    - Does not display variables' values
    - Suspends program execution when the expression
      becomes true
