The strip at the bottom left of my screen indicating line endpoint, mid point, centre and tangent of circle etc has disappeared.
Can anyone tell me how to retrieve it?
Are you talking about the OSnaps icon or the entire Status Bar at the bottom of your screen? The Status Bar has icons for Dynamic Input, Polar Tracking, Object Snap, Object Snap Tracking, etc. AutoCAD 2009? First try right-clicking on the Status Bar and see if that brings up anything where you can enable/disable what tools are showing.
