I am trying to build up our logo using MetaFONT with little
success. The logo has areas bounded by curved and straight lines. I
am trying to use the draw and flex commands of MetaFONT with no success.
What am I doing wrong? Could someone steer me in the right direction?
I keep getting the error:
! A tertiary expression can't begin with `..'.
<inserted text>
0
<to be read again>
..
If I leave out the `..', it gives me an error and tells me it inserted it for
me. HELP!!!!!
Thanks alot in advance.

That plus dumping the .. on the last line (each segment joined with "&" should be a complete path in itself) should take care of most of the problem. The end result should look like piece0 = z1--z2--z3--z4 & flex(z4,(161,11.5),z5) & z5--z6--z7--z8--z1 & cycle; -dh --- Don Hosek "Other people get into occupations by dhosek@ymir.claremont.edu accident or design; but writers are born. dhosek@ymir.bitnet We have to write.
