|SAS Component Language: Reference
two mechanisms for handling error conditions:
- The program halt handler
- Program halt handlers typically allow your application to
print a message, save some information, and then either try to continue execution
or halt the application. The SCL generic program halt handler is sort of
an all-purpose routine for handling program halts that occur for a variety
of different reasons at any point in the program.
- The CATCH and THROW statements
- The SCLException class and the CATCH and THROW statements
enable you to define specific exceptions and recovery routines that are specific
to each exception. You can define the exceptions and recovery routines in
the locations in your code where the exceptions may be encountered, thus making
error recovery code a natural part of the program.
