Simple DXF File Format Question

[rbRannoch]

I'm writing software to create DXF files.
I started by drawing a circle. That works. I see the circle in my DXF
viewer.
I then added a TABLE entry to create a DASHED line. The viewer accepts
that as valid input.
I then added the following just above the CIRCLE creation code:

6
DASHED

I expected the circle to become a dashed line, but it's still a solid
line.
Any ideas on how to make the circle draw as a dashed line?
