While paused during debugging (at a breakpoint, etc.),
you made a change that prevents execution from continuing.
You may have redimensioned an array, changed procedure
arguments, or edited some other declarative statement.
Use the dialog box and either:
■ Choose <OK> to keep the change and restart the program.
■ Choose <Cancel> to undo the change in your program
text. (You can do this if restarting interferes with
your debugging strategy.)
