What I'm trying to do seems fraught with problems and I thought I'd
ask my question again with more details.  Thanks to those who suggested
fill-pointers and treating a string as an array of characters, but I
am still having problems.  What I want to be able to do is parse sentences
from an input file, delimited by periods.  Other than periods, only a-z, A-Z,
slash (/), and dash (-) are considered non-white space.  Words are delimited
by white space.  What I want to create is not a string but a list component
(I discovered setting *print-escape* to nil to disable double quotes and
this should help).  So, in reading
            "This is sentence 1.
               This is * sentence2." 
I am trying to create:

( (THIS IS SENTENCE (NUMBER 1))
  (THIS IS SENTENCE2)
)

How can I coerce the string into being a list component??  This has
me stumped!  Thanks in advance.
