on error return   statement

on error return

Use this statement to reinstate FutureBasic's standard error checking routines. After this statement is invoked, FutureBasic 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 FutureBasic's error checking, use on error end.
