COMMAND NAME: DrawLine
/DRAW,{V|H},{{Row}|{Col}},{Start},{End}[,{Speed}[,{Character}]]
/cw
Draw a vertical or horizontal line on the screen using
»cy«{Character}»#«.
»cy«{V|H}»#« »ye«V»#« = vertical line, »ye«H»#« = Horizontal line.
»cy«{{Row}|{Col}}»#« The »ye«Row»#« (horizontal line) or »ye«Column»#«
(vertical line) at which the line will
be drawn.
»cy«{Start}»#« The starting column or row for the line.
»cy«{End}»#« The ending row or column for the line.
»cy«{Speed}»#« The speed at which the line will be
drawn. A higher number represents a
slower speed.
»cy«{Character}»#« The character with which the line will
be drawn.
.pg clr
All »ye«rows»#«/»ye«columns»#« are checked for validity.
If the speed is not specified or is zero then the line will
be drawn at »wh«full speed»#«.
If no character is specified, then a vertical bar (»cy«ASCII
179»#« "»ye«│»#«") will be used for vertical lines and a horizontal
bar (»cy«ASCII 196»#« "»ye«─»#«") will be used for horizontal lines.
Variables appearing in all tokens are expanded.
If »cy«{end}»#« is greater than »cy«{start}»#« then the line will be drawn
from »wh«right to left»#« (horizontal) or »wh«bottom to top»#« (vertical).
