TIB: Line-command & TI-86




I browsed old mail-list archives, but didn't find anyone mentioning the 
problem I just noticed. 

My manual claims that you can draw a line by issuing a command 
line(x1,y1,x2,y2), which is quite correct. Then it also claims that
line(x1,y1,x2,y2,0) would erase that very same line. This would be very
useful for me, but my calculator just ends up complaining about arguments.

Hopefully this isn't a bug, I need that command:) So where is it?

I have 1.2 rom, if that matters...
