Re: stored procedure and return values

thanks michael.

i played around a bit today as from my point of view the behavoir isn't 
right - but as you say it can be argued... but what you think about the 
following... i've added a nearly empty err_handler

and then i get my -6 back.. but then i have another funny behavior. when 
i try to print any of the commented prints in the error handler i get a 
core dump - also when i try to execute it with a trace of > 1

here's the script again...

any idea what caused the core dump and why it works with an empty error 
handler?


thanks
