Hi Eric, check the samples - Rabbit cave - you may lock the  
verticality or horizontality of segment of line:

line border -id l153-922-620
   933.5 607.0
   adjust horizontal
   932.5 949.5
endline

Thbook p. 24

adjust <horizontal/vertical> . shifts the line point to be aligned  
horizontally/vertically
with the previous point (or next point if there is no previous  
point). The result
is horizontal/vertical line segment). If all line points have this  
option, they are aligned
to the average y or x coordinate, respectively. This option is not  
allowed in the plan
projection.
