General error handler usually shows standard error message, aborts application and records error number, program module name and program line number to database. In your particular example you could embrace CreateObject line in TRY... ENDTRY, though I don't see need in it if 'job_info' class is part of your project, i.e. it will be compiled into executable, so any typos would be found on testing stage.

>>Your program is supposed to have general error handling routine. Special cases are needed usually in case of some external factors, e.g. you try CreateObject('Word.Application') and you are unsure if MS-Word is installed on every user computer, and you want to alert user right away.

>>>Is this overkill, or do most programmers actually do this with every CreateObject request? Or should I just pay attention to what I am doing and rely on my manual testing to make sure I did it correcty?
