Peter,

Of a top of my head

lcSaveOnEscape = ON("ESCAPE")		&& Save previous ON ESCAPE setting
lcSaveSetEscape = SET("ESCAPE")		&& Save previous SET ESCAPE setting

SET ESCAPE ON
ON ESCAPE llUserCanceled = .T.
llUserCanceled = .F.
APPEND FROM ...

SET ESCAPE &lcSaveSetEscape
ON ESCAPE &lcSaveOnEscape 

IF llUserCanceled 
	* Process was interrupted by an user.
ELSE
	* Process completed
ENDIF
