if ( my_name() != "MrPicky" )
{
abort( "I don't want you to run this script, mister!" );
}
An example of abort() used for error-handling.
float mass = 5.0;
float volume = some_function(); // where some_function() may return 0.0
float density;
if ( volume_cf == 0 )
{
abort( "Error: Division by zero requested." );
}
else
{
density = mass / volume;
}
CLI Equivalent
Also available as the CLI command "abort," which will not be queued (similarly stops execution of all remaining commands when parsed).
