You can handle the errors with the CATCH procedure. Place something
like the following into the beginning of your code:

catch,error_status
if error_status ne 0 then begin ; will be executed on error
msg=!error_state.msg ; IDL's error message
; you can print the error to the log file:
if !journal ge 1 then journal,'; '+msg
; or place an error message on the screen:
button=dialog_message(msg,title='IDL Virtual Machine',/error)
; or do anything else ...
endif

Good luck, Heinz
