## BBF.Cancel

Cancel the current border basis computation.

### Syntax

BBF.Cancel():STRING

### Description

Cancel a currently running border basis computation. This will not invalidate the current computation but just interrupt it. The computation will stop after the current computation step has finished. If you cancel a non-interactive computation started by BBF.Finish you will return to the interactive computation mode. Please note that in order to use this function you have to start the ApCoCoABBFServer.

The output of this function is a status string.

@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. -------------------------------
