Hello Everyone,

I am a graduate student in the Computer Science Dept at Penn State. I
have 
been working on a project involving Garnet since the past 3 months and 
have a couple of questions.

1. Can you please tell me the properties of a vertical scroll. How do I 
tie it with the length of a window and what are the properties that can
be 
changed?


2. Say I am creating a line by the code:

	(create-instance 'abc opal:line
		          (:x1 x1)
		          (:y1 y1)
		          (:x2 x2)
		          (:y2 y2)
		          (:line-style opal:blue-line))

	Instead, I need to use something like this:

	(setf a 'abc)

	(create-instance a opal:line
                          (:x1 x1)
                          (:y1 y1)
                          (:x2 x2)
                          (:y2 y2)
                          (:line-style opal:blue-line))

When I try to do this, Garnet kind of skips over the create-instance and 
does not even give an error. Please let me know what I am doing wrong or 
how should I go about doing this.

Thanks in advance
Atin.
