OpenCASCADE problem with DRAW!

I installed OpenCASCADE DRAWEXE test hardness today and try to start with the example given at OpenCASCADE site!
I started as follow
Draw[1]> Draw[2]> av2d
Draw[3]> circle c 0 0 1 0 5
invalid command name "circle"

I got this error, invalid command name "circle". Can anybody tell me the reason! I am very new to the package! Any help!
With regards!
