The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

■ Adds a watch variable to the Debug window. This variable
  is displayed with the value from its module or procedure
  location. It is not watchable outside of this context.
 
■ Use watch variables to continuously watch the value of
  a variable or an expression as your project executes.
 
■ The message <Not watchable> appears in the Debug window
  if the environment cannot access the variable value.
 
■ Tip: Use Watchpoint rather than Add Watch to suspend
       project execution when an expression becomes True.
 
■ To add a watch:
    1. Type the variable name or expression you want to
       watch.
 
       Enter expression to add to Debug window:
       ┌─────────────────────────────────────────────────┐
       │                                                 │
       └─────────────────────────────────────────────────┘
       • The Debug window can display the value of an
         expression made of variables (for example, X + Y).
 
    2. Press Enter or choose OK to add the watch variable,
       ╔════════╗
       ║   OK   ║
       ╚════════╝
       or choose one of the following:
       ┌────────┐
       │ Cancel │  To cancel the operation
       └────────┘
       ┌────────┐
       │  Help  │  To get help
       └────────┘
 
■ After you choose OK, the variable name is displayed in the
  Debug window, preceded by the procedure name or module file
  name where the variable is located.
