You can display characters instead of strings - they're displayed
without extra spaces, as in write-char:

(for-each (lambda (i) (display (integer->char (+ 48 i)))) '(6 5 4))
or:
(for-each (lambda (i) (display (string-ref "0123456789" i))) '(6 5 4))

Using write-char is still more efficient:

(for-each (lambda (i) (write-char (string-ref "0123456789" i))) '(6 5 4))
