Abort

Abort[]

generates an interrupt to abort a computation.

Details

  • You can call Abort anywhere within a computation. It has the same effect as an interactive interrupt in which you select the abort option.
  • You can use Abort as an "emergency stop" in a computation.
  • Once Abort has been called, Wolfram Language functions currently being evaluated return as quickly as possible.
  • In an interactive session, the final result from an aborted computation is $Aborted.
  • You can use CheckAbort to "catch" returns from an abort.
