Well, you can use a non-modal dialog with a Cancel button, but the hard part is how is the codeblock going to determine when the button is pressed?

Perhaps you can use the oDialog:cargo property to hold a flag which defaults to .T. and when the button is pressed, change the flag to .F. and then the codeblock would see the change the next time through the loop (assuming the codeblock is in a loop).
