chicken-spock question

Greetings -
I have a one-line file called test.scm with contents:
(write-char #\*)
At the command line I get:

user@computer:~/tmp$ csi -qb sfib_do2.scm
*user@computer:~/tmp$
user@computer:~/tmp$ chicken-spock -runtime test.scm -o test.js
user@computer:~/tmp$ node test.js
*
user@computer:~/tmp$

Why the newline after the "*" when I run test.js? Is there any to suppress
it?

regards,
NT
