ON ERROR RETURN Statement (+) Appearance (+) Standard Console Syntax ON ERROR RETURN Description Use this statement to reinstate FB's standard error checking routines. After this statement is invoked, FB will display an error dialog and halt the program when a file error is encountered. If your program has established its own ON ERROR FN vector, it will be ignored. If you wish to return control to your internal routine or turn off FB's error checking, use ON ERROR END.
