cdr /ku'dr/ or /kuh'dr/ vt. [from LISP] To skip past the first item
from a list of things (generalized from the LISP operation on binary
tree structures, which returns a list consisting of all but the first
element of its argument). In the form `cdr down', to trace down a list
of elements: "Shall we cdr down the agenda?" Usage: silly. See also
loop through.
Historical note: The instruction format of the IBM 704 that hosted the
original LISP implementation featured two 15-bit fields called the
`address' and `decrement' parts. The term `cdr' was originally `Contents
of Decrement part of Register'. Similarly, `car' stood for `Contents of
Address part of Register'.
The cdr and car operations have since become bases for formation of
compound metaphors in non-LISP contexts. GLS recalls, for example, a
programming project in which strings were represented as linked lists;
the get-character and skip-character operations were of course called
CHAR and CHDR.
