	[ ] 
[-] testcase do_except_example () 
	[ ] STRING sTestValue = "xxx" 
	[ ] STRING sExpectedValue = "yyy"

		[ ] TestVerification (sExpectedValue, sTestValue) 
	[-] except 
		[ ] ErrorHandler () 
	[ ] // Continue with testcase 
	[ ] ...

Notes

The do...except statement allows a possible exception to be handled by the test case instead of automatically terminating the test case. If an exception is raised while the do clause (statements1) has control of the script, control immediately jumps to the first statement in statements2 in the except clause, which often is a call to one of the built-in 4Test functions that gets information on exceptions.
If no exception is raised while statements1 has control of the script, control jumps to the first statement beyond the do ... except statement. The statements in statements2 are not executed.
