# Abort

 Abortgenerates an interrupt to abort a computation.
• 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, Mathematica 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.
Abort execution of a sequence of commands:
A function for doing fixed-point iteration that aborts if the value gets above a certain limit:
An unstable iteration:
A stable iteration to approximate GoldenRatio:
Abort the numerical solution of a differential equation if the solution would become complex:
