If your program had to locate the details of an employee and this information could not be found, you would have encountered a fatal error situation indicative of some sort of database corruption.  In such a situation you might use the application error handler like this:  

Fetch Fields(#SURNAME) From_File(PSLMST) With_Key(#EMPNO)
If_Status Is_Not(*OKAY)
   Invoke #AvFrameworkManager.avHandleError Curr_Comp(*component)
       Curr_Rout(ButtonHandler) Curr_Cmd(FETCH)
       Curr_Info('Employee details could not be accessed.')
       Curr_Retc(#io$Sts)
Endif

The standard error handler then does a number of things (depending up on how your Framework is configured) including:

• Displaying the fatal error details to the user.

• Recording the error details in a file.

• Emailing the error details to a nominated support email address.

• Terminating the Framework.
