|   I've looked in CLTL1 and CLTL2 (I don't have access to the ANSI Common
|   Lisp standard, alas), but perhaps I'm missing something:
|   	Is there any way in Common Lisp to read a sequence (of characters
|   	or bytes) of a specified length from a file all at once?

ANSI CL has `read-sequence', which destructively modify a sequence with
elements read from a stream, and `write-sequence', which writes elements
from the sequence directly to a stream.  "An efficient implementation is
more likely to exist for the case where the sequence is a vector with the
same element type as the stream" (from the standard).

the problem with this "information superhighway" is mainly that if you ask
people to go play in it, they don't even understand when they get run over.
