SYMPTOMS
If you press ESC during a user (or dynamic) dialog box definition in a WordBasic macro, Word halts the macro and the following error message occurs:

WordBASIC: The macro was interrupted.

RESOLUTION
To prevent a macro from halting when you press ESC in a user dialog box, you must trap the ESC key using the DisableInput statement.

The following sample macro demonstrates the correct use of the DisableInput statement.

Function DialogFunction(identifier$, action, wvalue) DisableInput 1 Select Case action Case 1 Case 2 If identifier$ = "Cancel" Then DialogFunction = 0 For xyz = 1 To 50 Print "Cancel pressed" Next xyz Else DialogFunction = 1 End If        Case Else End Select End Function

STATUS
This functionality is by design of Microsoft Word.

MORE INFORMATION
This use of the DisableInput statement conflicts with the information in online Help for the DisableInput command and on page 340 of the "Microsoft Word Developer's Kit." Both resources state that "DisableInput does not affect the use of ESC for canceling a dialog box." This statement is not true for dynamic (user) dialog boxes, for which DisableInput does prevent the ESC key from interrupting the macro.
