There is lots of documentation on the web on doing I/O in Scheme.
The simplest thing is the Scheme "read" command, which reads a Scheme-
formatted input file into a variable.
For example, suppose you had the a file foo.dat containing the
following text, including parentheses:
(1 3 12.2
14.5 16 18)
In Scheme, you would then write
(define port (open-input-file "foo.dat"))
(define foo (read port))
(close-input-port port)
Your variable foo would then be a list of numbers '(1 3 12.2 14.5 16
18).
