invoke-restart-interactively restart => result*
restart---a restart designator.
results---the values returned by the function associated with restart, if that function returns.
invoke-restart-interactively calls the function associated with restart, prompting for any necessary arguments. If restart is a name, it must be valid in the current dynamic environment.
invoke-restart-interactively prompts for arguments by executing the code provided in the :interactive keyword to restart-case or :interactive-function keyword to restart-bind.
If no such options have been supplied in the corresponding restart-bind or restart-case, then the consequences are undefined if the restart takes required arguments. If the arguments are optional, an argument list of nil is used.
Once the arguments have been determined, invoke-restart-interactively executes the following:
(apply #'invoke-restart restart arguments)
(defun add3 (x) (check-type x number) (+ x 3)) (add3 'seven) >> Error: The value SEVEN was not of type NUMBER. >> To continue, type :CONTINUE followed by an option number: >> 1: Specify a different value to use. >> 2: Return to Lisp Toplevel. >> Debug> (invoke-restart-interactively 'store-value) >> Type a form to evaluate and use: 7 => 10
If prompting for arguments is necesary, some typeout may occur (on query I/O).
A non-local transfer of control might be done by the restart.
*query-io*, active restarts
If restart is not valid, an error of type control-error is signaled.

invoke-restart-interactively is used internally by the debugger and may also be useful in implementing other portable, interactive debugging tools.
