25.2.23 /, //, /// | Variable
  Value Type: a proper list. Initial Value: implementation-dependent. Description: The variables /, //, and /// are maintained by the Lisp read-eval-print loop to save the values of results that were printed at the end of the loop. The value of / is a list of the most recent values that were printed, the value of // is the previous value of /, and the value of /// is the previous value of //. The values of /, //, and /// are updated immediately prior to printing the return value of a top-level form by the Lisp read-eval-print loop. If the evaluation of such a form is aborted prior to its normal return, the values of /, //, and /// are not updated. Examples:
       (floor 22 7)  3, 1
       (+ (* (car /) 7) (cadr /))  22
Affected By: Lisp read-eval-print loop. See Also: - (variable), + (variable), * (variable), Section 25.1.1 Top level loop Allegro CL Implementation Details: None.
