Hi,
I am learning guile and scheme. I want to draw a triangle, but the
machine always responsed me a warning. see below
guile>(define test-bb (filled-triangle 0 1 0 -1 1 -1))
standard input:10:4: In expession (filled-triangle 0 1 ...):
standard input:10:4: Unbound variable: filled-triangle
ABORT: (Unbound-variable)
guile>
my system is debian.

It looks like you're trying to do some kind of graphics programming
with Guile but don't have the right libraries loaded
("filled-triangle" is not, to the best of my knowledge, part of R5RS).
Perhaps you're missing a use-modules expression?
It would be helpful to know more about what you're trying to do here.

Oi veh, you'r right ;-)
"filled-triangle" is most likely the function exported by DrScheme's
fun-graph techpack. Somehow the OP's instructor failed to mention
that the exercises are DrScheme specific.
