errorDialog errorMessageText

HyperCard sends the errorDialog message and its text to the current card if it encounters an error when the lockErrorDialogs property is set true.

(In such a case, the ordinary error dialog box is not displayed.)

errorMessageText is the contents of the error dialog box that would be displayed if the lockErrorDialogs property were false.


on errorDialog what
  if what is "User level is too low to edit scripts." 
  then set userLevel to 5
end errorDialog
