<LI>The character used to draw the vertical line is system dependent.
|
|
If available, a line drawing character is used. Drawing a line that is partially
|
|
off screen leads to undefined behaviour.</LI>
|

<LI>The function is only available as fastcall function, so it may only be
|
|
used in presence of a prototype.</LI>
