If you omit the WITH RESUME keywords, the next statement that executes
after an exception occurs depends on the placement of the ON EXCEPTION statement,
as the following scenarios describe:
- If the ON EXCEPTION statement is inside a statement block with a BEGIN
and an END keyword, execution resumes with the first statement (if any) after
that BEGIN ... END block. That is, it resumes after the scope of the ON EXCEPTION
statement.
- If the ON EXCEPTION statement is inside a loop (FOR, WHILE, FOREACH),
the rest of the loop is skipped, and execution resumes with the next iteration
of the loop.
- If no statement or block, but only the SPL routine, contains the ON EXCEPTION
statement, the routine executes a RETURN statement with no arguments, returning
a successful status and no values.
To prevent an infinite loop, if an error occurs during execution of the
statement block, then the search for another ON EXCEPTION statement to trap
the error does not include the current ON EXCEPTION statement.
