undrawEnterFun

undrawEnterFun( ) 
=> t / nil

Undraws any rubberbanding shapes. Called when an enterfunction is active. If you enter data in the window, rubberbanding resumes.

None

`t`	The undraw is successful.
`nil`	There was no enterfunction pending in the current window.

The prompt “Next” appears in the CIW, and line segments connecting p1 and p2, and p2 and p3 appear on the screen.

enterPolygon( ?prompts list("First" "Next")
    ?pointlist list( p1 p2 p3 ) )

Erases the segments, but the prompt remains to signify the enterfunction is still active.
