Sybase : How to disable return status when executing stored procedure?

Let’s say I want to run a stored procedure in an isql session and then send the result set via mail:

but then you get this “(return status = 0) which is not that nice. So for some time I’ve been using grep -v “return status” or sed on the result file to remove the unwanted line until I’ve found out that you can actually disable printing of the return status with a nice command:

Quoting the documentation:

controls sending of a return status TDS token back to the client. set proc_return_status off suppresses sending the return status token to the client, and isql client does not display the (return status = 0) message. The default for this parameter is on.
