Hi Yann00,
Not sure what you're trying to achieve exactly, but the first `printf`
might be the culprit. In SKILL/SKILL++,
printf("foo")
is interpreted as:
(printf "foo")
whereas (notice the extra space):
printf ("foo")
is interpreted as, well, an error. (Technically, a reference to the
`printf` variable, and an attempt at calling a string.)
Hope this helps,
Damien
