The catch clause is used to handle the exception. To raise
an exception, use the throw statement. When you want to trap
potential errors generated by a block of code, place that
code in a try statement, and follow the try statement with a
catch statement. The catch statement is used to process the
exceptions that may occur in the manner you specify in the
exception_handling_block. The following example demonstrates
the general form of the try statement with the catch clause.
In this example, the script continues executing after the
error message is displayed:
try {
do_something;
}
catch (e) {
TheApplication().RaiseErrorText(Clib.rsprintf("Something bad
happened: %s",e.toString()));
}
