If you cancel a non-interactive computation started by BBF.Finish you will return to the interactive computation mode.

@return Status string.

#### Example

Use ZZ/(32003)[x, y, z],DegLex; I:=Ideal(-4*x^200, -4*y^2, 5*z^2); BBF.Init(I); BBF.Finish(); BBF.Cancel(); Computation started. ------------------------------- Current computation will stop after current step has finished. -------------------------------
