- The one-and-only official DWB pic accepts line by A,B
- just fine. It means "relative direction"; e.g.
- line by 1,1 by 1,-1
- means "draw a line at 45 degrees from the current
- position, then -45 degrees, each segment being the
- default line length."
- The documentation is exceedingly circumspect on the
- semantics of "line by" so I will guess that you have
- a reverse engineered version of pic (eg from groff)
- and the person doing the reverse engineering couldn't
- figure out what it meant.
- My conclusion is that the more inscrutable our
- documentation, the more difficult our code is to
- clone. I'll try to keep that in mind.:-)
