(I) This one-line program shows an error message, no problem: (error "We want to see this error message!") ;; (II) A similar program doesn't show the message, if it has been compiled: (error (format #f "We want to see this error message!")) ;; The compiled program II says: "Error while printing exception". ;; It doesn't matter which function produces the string for the error message. ;; The compiled version does not work, if the message string is the returned ;; value of a function. The pure example: (error ((lambda () "If compiled we won't see this error message!"))) Best regards, Klaus
