polylines

Hello
Can someone help me draw polylines anti-clockwise, not using Halfwidth or Width? As an example I want to draw a polyline from startingpoint 100,100 to 100,150 then to 200,150 and further to 200,200 and then to -100,200. After that I want to draw a 1/4 arc with a diameter of 50 (@50,50) to the right, etc.
Does anyone have a good link to a webpage about drawing polylines?

Have you tried the help file?
here's my text screen of that exercise ( pline width was set to .5 when I started, and I was zoomed in too close):
