1.3.12 Interrupting Calculations

There will probably be times when you want to stop Mathematica in the middle of a calculation. Perhaps you realize that you asked Mathematica to do the wrong thing. Or perhaps the calculation is just taking a long time, and you want to find out what is going on.

The way that you interrupt a Mathematica calculation depends on what kind of interface you are using.

Alt-Comma or Command-Comma	notebook interfaces
Control-C	text-based interfaces

On some computer systems, it may take Mathematica some time to respond to your interrupt. When Mathematica does respond, it will typically give you a menu of possible things to do.

continue	continue the calculation
show	show what Mathematica is doing
inspect	inspect the current state of your calculation
abort	abort this particular calculation
exit	exit Mathematica completely
